Hm, I don't remember Street Legal having this good a set of mods.
Also, has that IS got an RB26? Heresy, get a 2JZ in there.

I guess you mean all cars in any game? In that case...
(Disclaimer: I enjoy crap cars.)

My GT86 in Gran Turismo 6. I love this car, it drives so sweetly in just about any situation and is infinitely adaptable to different tyre choices and performance levels.

My Daihatsu Copen. An understeery little bugger, until you put some good tyres on. Then you have a gokart that screams along at 10k RPM, excellent fun.

Racing beige Volvo 240 GLT. Surprisingly entertaining to drive, and can do a mean burnout if persuaded.

Daihatsu Midget II and Subaru 360. Again, just because they are a bit crap and they are great fun.
I have plenty more, mostly old Japanese stuff, but these are my current goto cars. Lotus Elise, Sprinter Trueno BZ-R, I just don't have good pictures of them.
