2002 BMW 5 Series 525i 4dr Sport Wagon (2.5L 6cyl 5M)
Although I've only had this car for 3 months and 5K miles..so far so good. Weak spots are definitely the cooling system (water pump, pullies) and leaking valve covers. Although if you can turn a wrench...fairly easy to DIY and numerous forums that cover DIY's. Car absolutely hauls...one of the fastest "family" cars I've ever owned. Purchased for $12200 with 50,XXX miles on the odometer. Overall, very happy with this car. As for fuel mileage, I expected much worse since I can't keep my right foot off the floor board. City / Town is 19.9 average and recently got 24.6 on a 300 mile trip with the set at 80 mph. Nice surprise since most were claiming much lower figures. Stereo stinks.
Size of cargo area. Absolute "hold on your hat" acceleration. Smooth shifting transmission. Exterior profile (awesome). Compliments and head turns from people that look at it. :) Memory Seats.
I'm sure most complaints have been addressed since 2002. Stereo reception LUMBAR SUPPORT FOR SPORT SEATS!! Standard Bluetooth ($700 for the bluetooth kit???) Sliding cargo floor should be standard.
