I had one for a little over a year. The cooling system is the weak link, so I changed every hose/fitting when I got it. I needed to change the filter housing gasket (which leaked) so I just did it all while I was "in there". Ironically, I removed that Y pipe behind the head (what a bitch!) but did not swap it out with the Febi unit I had as the BMW one looked just fine... It later failed...
It's not as bad if you remove the valve cover, and that's a good time to renew the plug seals, and that little seal in the front of the cover which hardens up over time. All the hoses/fittings/seals cost me less than 250 clams.
There's a good owners forum where lots of good information can be sourced. Just like this place...
Great running/shifting car. The engine is very smooth throughout the range, and got me almost 33 mpg on the road. Handled great. The hatch provides lots of flexibility and storage. I only got rid of it because I wound up buying a TDI, which is getting nearly 50 MPG's.
