Replaced back tires.
I had to replace a loose alternator belt.
One hose leaked, so I replaced all the hoses.
Had to replace the water pump.
Drivers side door makes a weird noise when opened and closed.
Front passenger side window works when it wants to.
Chrome molding around the driver's side door fell off.
This is my first car, and unfortunately it has had me on the side of the road three times. Two out of the three problems (leaky hose, disconnected battery cable) were remedied while on the road and only once (failed water pump) did I have to have it towed to a mechanic. I have learned a lot about cars this year.
I love the way the car handles turns.
I'm still not used to the loud European engine.
This car still looks good inside and out, despite its age. You can tell its quality is better than a lot of cars that are newer.
The loud engine may be a leak in the exhaust header or down pipe; my '84 is reasonably quiet. The hitch in the driver's side door is probably a check strap in need of grease, or in some cases, with a broken mounting.
My passenger window also only worked when it wanted to. I pulled and disconnected the switch from the middle console and cleaned it with alcohol and now it works like a dream.
I have a 318i also, and I've only had a few problems, one being the power windows. For a while the passenger window worked when you pressed the button a certain way, but after a while both windows and the antena (that would go up when car was turned on and down when it was turned off) all stopped working at the same time. Still waiting to see how to fix it, first thought it was a fuse, but apparently not.
