The interior trim is very worn, and the velour upholstery attracts dirt.
The electric windows have decided to only work when they feel like it.
The central locking has decided I can open the driver's door from the inside only.
What I thought was a knackered shock absorber actually turned out to be a rusted axle, so was very surprised when the front drivers' side wheel fell off. The axle had rusted right through, and had snapped.
This is a seriously comfortable motor. It cossets you and powers you along at surprisingly high speed.
The fuel economy is better than I expected for such a large, heavy car. In town it is poor, but motorway driving produces over 40 mpg. The fuel tank is huge, and cost me £55-
I can't believe the front driver's side wheel actually fell off. There must have been something very seriously wrong with the anti roll bar and/or the wheel bearing or the track control arm for that to happen. I have owned a 1985 100 CD for about 6 years now. The only things that usually go wrong are the starter motor (best replaced with one from a 5 cylinder Passat),the rear brake calipers (handbrake mechanism seizes-lubricate regularly, using silicone brake fluid helps),and the throttle valve, which gets dirty inside causing idling problems, but can be removed and cleaned quite easily.
