BMW 5/6/7/8 Series 1980-2008
BMW’s 6-Series coupes have been with us since 1977, won races and lots of hearts, yet unless you crave one of the ultra-rare M6 versions they aren’t insanely expensive either.
Cheaper and still practical for regular use, the 645i Coupe can be found in excellent order at under $30,000.
| Future classic: BMW 635 CSI
The earlier, V8-powered 840Ci is getting cheaper too but parts issues make these a difficult choice. For a practical sedan with good performance, consider 540i-550i cars which in usable condition cost $5000-15,000.
| Smart classics: BMW 745i E23
Collectors remain keen on the 1980s-shape 535i but are less enthralled by later E34 Series cars or the big, more complex 735/750/750iL limos.
