Having owned a Mk2 8V GTi and test driven (very hard, saleman wasn't pleased
but since I was seeking (on the dealer's behest) a potential replacement
Autocross car, I felt the "need" to JNR test it) the 1.8 liter 16V GTi, I
actually found the 8V more fun (better low end torque, less weight, more
tossable), and they're WAY better on gas. Never ended up driving the even
heavier, big bumper 2.0 16V's. In any case, nowhere near as nice as an Audi
A4, and in terms of crashworthiness, (and flat cargo floors), uh, the A4
avant wins there, while being nearly as good on gas (at least a 1.8T/2.0T).
