Here's a car I made - the Gazelle. Similar proportions to a Chevy Impala, but a 4-seater RWD sedan. 4 trims with 2 engines and 2 transmissions.
5.0-liter V8 DOHC, 330hp, regular gas, 7-speed single-clutch automated manual.
Same 5.0 V8, but mated to a 7-speed manual.
The RS versions have a 6.0-liter V8 DOHC making 410hp on premium gas. This one has the 7-speed automated manual...
... and this one has the 7-speed manual. I gave a pic for each trim to show the differences in overview stats, as well as to show off the car from multiple angles. (Also, not as important, but the car was designed with just default parts, no add-ons.)
