A friend could record it.
Mave, does it need any mantenience on the engine?
Do you go to the official volkswagen dealer or do you go fix stuff on the car somewhere else?
My dad had an alfa romeo 33, about 128000km, the engine kinda started dying, if you did over 100km/h it would start vibrating, and to start it up you needed about 10 secs, and when it started black smoke came from the back of the engine.
My dad took the car to the official alfa romeo dealer, and guess what?
IT GOT WORSE!
It took even more to start, the engine started dying randomly, and they didn't oil the damm accelerator so it was hard as hell.
Then my dad got pissed off and sold the car.
I went to see the car and he said he used ford escort parts.
The car could run about 140 without doing almost any sound
It looked freaking cool cause he tuned it.
And it started like a new car.
