While nothing is really WRONG with the car, it feels as though it is rapidly deteriorating.
The two plastic trim pieces that cover the C-pillars over the back doors have both come loose. One refuses to remain flush when popped back into place.
Black plastic trim piece in the passenger door fell off. I popped it back into place.
The car had a HORRIBLE rattle in the fuse box area. I had to thoroughly investigate it, and remedied that situation by tucking a folded cigarette box between two plastic bits (classy).
Interior plastic scratches easily. Exterior bits made of plastic lose their paint in the car wash (bumpers, mirrors, etc.)
Minor occasional vibration at idle.
Snow/ice buildup on window seals causes the windows to freak out, going up, then down, then up again. When this happens the one-touch auto up/down feature is disabled and needs reset. Also, something in the window-winding mechanism has etched a deep line in the driver's window glass.
Windshield spontaneously cracked when pulling out of the driveway in very cold weather (-26 F). This cold snap also made the blower motor for the heater very buzzy and loud, but that went away as the weather warmed.
I have had many older European cars. I love them. I have had old Saabs, Volvos, Audis, Mercedes, BMWs, and even the odd Jaguar XJ6 and a Peugeot 505. I have also had three Mk2 Jettas. The two Jettas I had the longest were silver, and so, when I finally decided to grow up and get a "real" car, I bought a new VW Jetta, in silver. It just felt right.
This car is becoming like my old Jettas too quickly. It is beginning to buzz/rattle like they did. It is beginning to vibrate at a stop in drive like the 88 did. Things are falling off of it like my old VWs. However, I paid no more than $1500 for either of the old ones. This new one was $15k. All I can hope is that it runs for a long time like my old ones, despite their "quirks." However, I don't foresee this car running in 15-20 years. I don't foresee it becoming a cult classic, or being fondly remembered. The car is mediocre at best, and even I, the king of 'quirk', cannot forgive it. But I see tons of Volkswagens on the road, duct tape holding up windows, brake/tail/headlights out, dashboards lit up like Christmas trees from all the warning lights, just going and going and going... that's the best I can hope for from this car, I think. It's falling apart in typical VAG fashion, but I hope it continues to run for a long time, in typical VAG fashion.
