Here are all the available chassis types (Although more may be added later)
These will all be available in a wide variety of sizes and proportions.

Turn it around and Make VW Beetle Chassis 
nice work,
i can make a ute nice
Looks great 
but there is just one thing:
Are you sure you don’t mean body-on-frame instead of unibody. 
A derp! typed in the wrong listing there, ill fix that 
They look amazing. If you need more ideas just google for TVR ones
Great update!!
Looks good, very exited to see how this unfolds
Woah, those look really good indeed! Now I just imagine the pain in the ass they must have been to make. xD How will you be able to scale them with car size? Different fixed-sized models or are you planning on having length and width scalable by the player?
Different fixed sizes - if you look at real cars you’ll find that there is really only about 7 different sizes of wheelbase/track/chassis length, so we can cover a lot of different cars with fixed sizes (plus you can adjust how much the body overhangs the chassis)
in the words of Borat “Very nigh-ssss”
looking very nice! 
although, will you take into account different engine placings? i would assume that they would have different chassis needs
Yeah, they’re cool! ^^
Good work, keep it up! 
Oh, yeah those are front engine only - there are mid/rear engine ones in the works too
You mean like the carbon fibre tub with steel frame pictured on the far right? (with slightly more tubes and each of them thinner admittedly)
Indeed.
