#1 Vw Golf Mk2 A-Class, Just pop the 1,8T under the hood, small tire and engine upgrades and youre good to go.
Suprised me on the dirt roads even it is FWD.
#2 Ferrari 288 GTO A-Class, really good on short courses and sharp turns.
Just needs weight reduction, race gearbox and clutch and something small for the engine. I like it more than F40 or F50 even.
