Mastin SA is a company specialized in pick-ups, SUVs and off-road vehicles (with a few exceptions). It was part of a family of cars and engines in ADM but in 1971 it splited and form an independent company. Although it ran solo for a few years, by the end of the 80s it was acquired by Meliora Automotive..
where is your handsome profile picture ( no homo )
Hahahahaha xDD
It got to go, I will probably add a new one when I take a new photo 
After the separation in 2 brands, and some re-tooling and stuff, Mastin was in a hurry to launch their own models, and by 1973 2 models were completed.
The first one was the Boyero, a Van that came in 4 trims (but you could ask for different options at the dealer, with virtually any number of trims). It was powered by new engines developed in-house, a pushrod L6 or V8 called the Durango family.
The economy was still recovering from the oil crisis, so it was not a particularly good idea to sell guzzling vehicles, but the company was pretty well known from their times at ADM so it has no major problem selling the new product.

###Boyero Pasajero Largo - $3,992
###Boyero Lux - $5,702
###Boyero Cargo - $3,470
#1973 Vaquero [corporate]3 trims[/corporate]
The second model that was presented in 1963 was the Vaquero. It was the attempt of Mastin to fill both utility and coupe buyers.
It was build on a ladder chassis with steel panels, with the classic Mastin set-up, FR with solid axle leaf in the back. It came with 3 different engines, the Durango L6 used in the Boyero (featuring a brand new 3 carbs system) and the Durango V8 also available in the Boyero. But for the highest trim, the sport one, a re-tune V8 was available with 209hp, paired to a 4 speed manual, capable of a top speed of 228 km/h and do 0-60 in less than 7 seconds.
The sales of the models were rather weak, specially for the high price tag for the v8 models, but as today, they stand as true classics, but most modern users swap the Durango V8 for a re-worked Classic Mastiff or a later Mastiff Gen engine.
###Vaquero Estándar - $3,058
###Vaquero Entusiasta - $3,723
###Vaquero Sport - $3,980
Those vans and utes are a great way to start off the Mastin brand as a standalone marque. Incidentally, one of the Enforcer-exclusive vehicles in APB: Reloaded was also called Vaquero. I think of it every time I hear that name.
Wow top notch designs dude bery very cool
Absolutley gorgeous. Perhaps its my limited knowledge of pick-up trucks and utes, but this really puts me in mind of the Subaru Brat.
#1975 Borzoi
Completing the full line-up of trucks and utility vehicles, Mastin presented the Borzoi, a SUV/pick-up with some off-road capacities, taking the role from the previous ADM Mastin Familiar.
Thanks to the new environmental laws, all models were required to fit a catalytic converter, sucking power from the Durango V8 engine used in the models, passing from 164hp like in the Vaquero to 149hp and 124hp in case of the L6.

'78 Vaquero 5.0
Vaquero (literaly, cowboy in english) is Mastin attempt to please fans of both coupés and pickups vehicules.
The previous generation was released in 1973 in 3 different trims, with mixed reviews and average sales.
Background
Mastin, being a company focused in utility vehicules, it saw the potential market for trucks such as the Chevrolet El Camino, plus the making of UTEs make lead in the future to the development of other vehicules apart from trucks and SUVs.
As part of the development of this new generation, Mastin decided to developed a new type of chassis, an hybrid between ladder and monocoque. This new chassis, allowed the Vaquero to be lighter than a traditional pickup with ladder chassis, while retaining some good resistance in the rear area.
For the engines, a new developed Mastiff V8 was available in 4.6L and 5.0L configurations, both of them using a all iron design with an OHV system and a single 4 barrel carburator, connected to an automatic transmission.
2 models were available, the LTD focused on the utility part and the 5.0, with a lower stance, focused more on driving and acceleration.

That is an interesting chassis design! I also feel like pickups should use unibody for the passenger compartment and ladder for the bed.
Mercedes Sprinters and some similar trucks have sort of a construction like that…
Black & white paint scheme
The malamute is Mastin’s first attempt to create an off road truck. Exteriorwise it was recognizable due his additional lights, 2 in the front and 2 on the roof and its big grill guard straight from factory.
Background
Back when Mastin was still part of ADM, there was a project of developing a Diesel L6 engine for light trucks application, but after Mastin splited from ADM the project was scratched and re-open again in late 1975. With the new engine in development (Most of it was done, except for the fuel system and the heads that were re-enginered to use a more simpler OHV system), the designer took the task to take Mastin’s new platform and transform it into a 4x4 truck. Some changes included the new solid axle with coils suspension front and back, as well as a more shorter front and bed. Some extra pillars for strength were added.
By 1978 the project was completed, and the results were very positive, giving Mastin a much needed boost sales, although the truck was very expensive due to its new Diesel engine. To try and mimic real driving conditions. the truck was tested in the mounains and villages in Jalisco in Mexico.

'78 Rottweiler Wagon 4 door
The 1978 Rottweiler was the succesor of the 1975 Borzoi, but with less number of trims. Mastin was still trying to find an identity within the market, and now that some of the models had been in the market for a couple of years, Mastin executives decided to re design must of the line up by 1978, taking now more time to the designing and engineering instead of rushing things up.
The Rottweiler was launched in november 1978 a couple of months after its sibling, the Malamute.
Background
Months later after the launch of the Borzoi, engineers started to work on the new chassis for the upcoming models, from the ground up. An anti corrosion ladder chassis with double wishbones in the front and solid axle leaf was the base of the design. During this time, the Malamute project was begining as well and eventually used the same platform, but heavily modified for a more off road oriented use.
The exterior design between the two models was similar, sharing some number of parts and panels, but the Kelpie design was less agressive in comparision to the malamute’s.
Finally, in 1978 was released to the market (US, Mexico and Canada) with 2 different trims. The 4 door wagon and 2 door pickup. Both using the same 4.6L Mastiff V8 used in the 1978 Vaquero.
It included a spare tire carrier

Wasn’t kelpie a gryphon gear vehicle? Not like those two will be easy to mix up 
You are right. I might change the name tho, kelpie sounds weird in my ears for a suv on the long run.

I don’t have much to show for Mastin until 1982, so here is some vintage ad. It is probably like a 2 page ad for magazines.
Following the 1978 second generation, the Vaquero received a minor facelift in 1982, with most of the changes being in the inside.
Vaquero Sport
History and development
Barely 4 years after the introduction of the Vaquero, it received a minor facelift. Some changes included a re-designed front facia (new main and secondary grills) and the indicators were integrated with the main beams.
Engineering wise, the suspension were revised and now it provided both more grip and comfort, as well as a greater towing and load capacity.
The drivetrain was also revised as well, the V8 options de-stroked 4.2L Mastiff V8 engine with 135hp, the 5.0L now produced 193 horses (13 compared to the previous version) and a new L6 option was also introduced for the cheaper trim.
Vaquero Premium
The new L6 engine was refered as Grifon, based on a similar architecture to the Mastiff V8. It had iron head and block with a pushrod system. At 2.6L it was rated at 98hp and 125ft-lb using a single 2-barrel carburator.
The cheapest trim began with the Vaquero Base, including the L6 engine paired to a 3 speed automatic + crawling gear with a simple interior and a simple AM/FM dual speaker radio. This was intended not only as the base version, but also as a cheap workhorse for those who didn’t need a full size pickup. Even at its small size and power could carry or tow 1.5 tons.
Next trim was the premium, with the 4.2L V8 engine paired to a similar 3 speed automatic + crawling gear transmission and an upscale interior, compared to more premium cars, with leather seats and some wood details in the main panel, plus a decent audio system.
Lastly, the Sport trim was intended as a take to the old american Muscle car. The 5L Mastiff engine was the only option, paired to a classic 4 speed manual gearbox, while mantaining all the interior comfort of the premium trim. The direct competitor was the ADM Galgo.
