Purchased a used Dinan 5, 540ia supercharged. I had owned a 1985 735ia before. Interior was very close to the 735. Power and handling was vastly better. 0-60 in under 5 sec and 60-0 makes your stomach turn. Corners are FUN. 90 degree corner at 60 kph and no problem staying in my lane and No tire squeal. Wow, I have driven many sports cars, but this defines sport.
After months of research and comparisons with MB and Lexus, I found my 525 5-speed. Considered a 98 but the 95 has the styling that won't look dated. After a year and 12000 miles no mechanical problems to speak of. Only gripe is brake light circuit warning light that has a mind of its own. Average overall MPG about 20 so far with the ability to get 28 or more on the highway if I can drive under 70 mph. Great car. Still under 100k so looking forward to many more ahead. Not a burner off the line, but better mileage than a v-8.
Bought with 75K miles on it, nikasil engine block replaced with alusil at 46K mi.. It has incredible power, comfort and highway cruising ability and is extremely well made. You can't beat the classic BMW four round headlights look that these cars have. The V8s do have some problem areas (radiator, intake manifold gasket leaks, valve cover gaskets that leak with age, etc)but any buyer that does his/her homework and buys a solid car won't regret it.
The power can be addictive and really comes on strong above 3500RPM. Overall quality of materials and solid structire make newer, cheaper cars feel like, well, cheaper cars.
Bought black with black interior BMW 540 used - 9 years old (nickname Vader). All my previous cars were just tools for traveling. Vader's comfort, solid construction, and performance made me 'fall in love'- feel safe and pampered. Superior quality leather seats and interior. Exterior is classic and elegant. Gets 19 mpg; engine has hp & torque to merge into highway traffic, and maneuver out of danger with ease. Headlights are more like laser beams. No one keeps brights in my eyes if I flash the hi-beams at them! Nikosil engine was replaced by a previous owner. Vader has been reliable daily driver, with only routine maintenance needed, and I travel 100 miles/day. This is one great car.
Performance, reliability, style, and comfort. On-board computer links with radio; can see which CD song or radio station is playing w/o taking eyes off the road. Also displays outside temp; trip miles; ave mpg; ave speed; and much more data.
