I purchased a 1989 2dr 325i with 125k on it. This was about a year and a half ago. I paid $3200.00 for it.
Week later the transmission went out ($1300.00)
Exhaust was rotted out, so I replaced it ($200.00)
Replaced the original BMW battery ($80.00)
Fuel pump went out ($400.00)
At this point the car was rolled off an embankment after clipping a deer. The little BMW rolled over completely and landed right side up. The car went a total of 70 some feet, after a bit of sliding. Dents here and there, no broken glass. Amazingly, the only thing that prevented me from driving this car home was a $35.00 tie rod and the fact that one of the wheels had been bent when the car slid sideways. I had a spare, but no tie rod.
The car held up amazingly well. $3000.00 later, the dents were out, and the car got a new paint job.
Water pump goes out ($150.00)
Water leaks throughout interior, had to get replacement carpets ($300.00)
Replaced the pressure regulator ($70.00)
OK, those were only the major repairs done to the car, not including the normal matinence (brakes, etc), or things like dash lights and AC. All and all, I dumped around $8000.00 into this car, not counting the original purchasing price. I once had three flat tires in two days. All from seperate incidents. On one of them I was not in a position to safely stop, so I was forced to drive on the wheel for a distance. It ended up being three new tires (made it four so they were equal) and a wheel in two days. This car was bad luck, let me tell you. Loved it to peices dispite the problems.
The only real problem left with the car was the only one I could not figure out. It not only stumped me, but many others. While driving normally, or upon start up, it would all the sudden act like it was running out of gas. It would sort of "putt putt putt" along, and would not exceed 25MPH. Pedal to the floor or not it made no difference. When left at idol, it would appear to be dying then catch itself back up again, repeating the process.
These incidents would last between five minutes and several days. Usually they were cured by revving the engine for several minutes. Eventually you would hear something sort of "break through" or "pass through" and the car would be normal again.
Does anybody have an idea what caused this, or better yet, a solution to this? This factor alone caused me to sell the car for $3000.00, taking a drastic loss. The fuel filter was changed several times, the car was not out of gas, fuel pump was in working order, and everything appeared to be ok. However the check engine light came on while this was happening. The light turned off once the car started running normally again. It was the check engine light down by the brake sensors, not the one that flashes if you have a brake light out.
Car was sold with 147k on her, and she would still do 0 - 60 in about seven seconds. Had to be running properly though.
All help is appreciated.
