Personally, the 1990 Ibishu Miramar GTz but if I had to choose an official, non-mod car, then it'd likely be either a Sunburst RS, an SBR4 TTS or a Hopper LXT-6.
My default, a 1978 Moonhawk with 15x9 wheels, BROWN, 4-Barrel Carburetor, custom suspension, and a bunch of other customizations that I have made to my personal preferences.
Either a barstow, because what else is there? 2nd choice would be a 200bx to have excellent handling. 3rd choice would be covet for mountain road racing.
I would get the Moonhawk Track just because of how good it sounds and handles for an older muscle car. EDIT: just now realizing I already posted here... Whoops!
It would have to be a toss-up between the '89 Ibishu Pessima GTz and the Ibishu 200BX LS. '80s and '90s cars just do it for me, especially Japanese ones...
For me the Hirochi SBR4 Hillclimb-Asphalt with the Turbos cranked to 38psi producing over 900bhp, I like going fast and I like AWD tunability
Probably the ETK K-Series with the widebody mod or the Hoonicorn Barstow, who could complain about 1000+ horsepower to all four wheels (for both cars)
Bruh, I would want a fully customized really fast but stylish etk 800 i could beat like anyone in a race with performance, and style
