Absolutely nothing, but I haven't had it for very long.
I only bought it this year, but nothing has gone wrong with it yet. It has done a lot of miles, but my mechanic had a look over it and said it looked sound.
The previous owner really looked after it and the modifications make it worth far more than the £1500 I paid for it.
It has a new turbo engine in it, but the previous owner put it in because he was a boy racer, not because the previous one had packed up.
Despite its age it has very little rust and if you do a few modifications on it and look after it, it will look terrific.
Prefers motorway driving and really opens up above 50mph. Makes a good growling sound when driving around the town - great for scaring small children and oldies!
The only down sides are the higher road tax and insurance, the upholstery could be a bit more sporty and electric windows might be nice. It took me a while to get used to getting it into 2nd gear because of the gear ratio.
Had a '95 Golf Match diesel as my first ever new car. Can't belive it would now be 9yrs old. I remember that the ride was very soft and made me feel sick while driving.
