Fuel Intake got clogged, causing the car to stall. ADAC fixed it on the spot for about 40 euros.
Moon-roof leaked sometimes.
Very reliable car that got great gas mileage. It's a very cheap car, I bought it for about 200 euros in 2000. Very basic, kind of a cramped feeling. It won't go over 120 km/h, which is a real pain on the autobahn, sometimes if I drove down a hill it would go up to 140km/h. The stock stereo was awful, very weak speakers. But it got the job done.
I gotta say that your car is additionally slowed down with gas fuel because it took some strength away from engine that is only 40 hp by default
Gas installing is pointless in car that is low on petrol.
