Bought my 1995 318i in 2005 with 165,000 km (about 102,000 miles) on it - it now has 217000km (about 135000 miles) on it. It also has rusted out rockers and right rear fender, cracked windshield, the cluster (mph,tach etc) no longer works, lower control arms are shot, struts shot, won't idle, and the drivers seat (it's cloth) is worn out.
I have replaced the alternator, starter, O2 sensors 3 times, MAF (twice) and innumerable other smaller items for a total repair bill of about $3000
I paid $5000 for the car in
2005...it's now worth about $500.
BMWs are fine...if you're willing to spend upwards of $1500 a year on repair and maintenance.
