#7 - BMW 540i Top Speed:
155 mph Average Cost: $5,000 (model year 1995-2003)
If it hadn't been for the E39
M5, the 540i might have been much more of a legend than it is.
Still, people are starting to recognize what an amazing
performance bargain they are on the used market. It was limited to
155 mph, but likely could have gone faster.
High-mileage examples are scarily cheap, but clean ones can also
be found for less than $5000.
