316k miles and still drives like a dream. This car has been in my family for 12 years and has not given me any major mechanical problems. This has been and will be the best car I will ever own. It has reliably performed throughout its service life. No bells and whistles, just a bare bones car that never acts up. I reliably changed the oil every 4k miles and did all maintenance myself. For a 21 year old car it shines up like a new penny. Beautiful, reliable, and a joy to drive. I will miss her when she's gone...ought to go to a BMW museum. What a joy.
I purchased this car off the showroom Floor in October 1991. I wished I could buy a new one again! This car has been a DREAM, it currently has 281,000 miles on the original transmission and engine. I've always changed the oil every 4,000 miles and have always used Mobil 1 Syn. OH! by the way...always make sure to change all your fluids (Brake, power steering, rear end, coolant as needed. This is the year 1991 where BMW went from a timing belt to a timing chain. The M50 engine also has a large-big pusher oil pump. I might be buried in this thing..............DiD I ever get my money's worth. Learn to work on the car yourself...it's not that hard. The only thing I had to change was the ECM....there's a place in Miami that will repair ECM's for $400.00 with a lifetime warranty....besides that just regular maintanance. This vehicle doesn't burn a drop of oil. Automobile of the Century!
I finally decided to give the 1991 525i a review. I only drive BMWs and the 525i is my 3rd beamer (automatic), I prefer manuals but... My 525i has 243,878 miles on it and it still rides smooth, tight and stiff. I did put a transmission in it at around 210k because the 3rd gear went out. Above all the regular maintenance and small things that goes wrong, like the cig, lighter(s) not working, I love this machine. It's the bomb.
I've had my 525i for about a year and a half, and have no regrets about the purchase. This car feels like a "real" car. It feels safe and solid, the 2.5 straight six is adequate, and the car handles well. The 50/50 weight distribution is one reason for this. The build quality is outstanding and the design seems straightforward and no-nonsense. It looks timeless, and as a used vehicle, I think one gets a lot for their money with this car. And besides, since this car is designed to be stable at 130 m.p.h., imagine how stable it feels at 70 m.p.h.! Since I enjoy fixing my own vehicles, I consider parts availability and dealership cooperation important. My local dealer has been obliging!
