Works 60% the time, Everytime.
My brothers got the gttdi 150 mk4. Not a bad car. I can only compare it to the S3. It shares the same chassis but they couldnt be further apart. I can see why the Audi is more expensive.
Golf is very wallowy, barge like. Interior aint as good as the Audi.
The leather seats in the golf are more comforable(softer) and the steering is lighter which is more enjoyable for steady driving.
Size wise very similar, luggage, passenger etc wise.
I think you can make the Golf look better more easily too.
I say 150 golf and revo it. Or A3 if you specifically like the looks of it.
