Doug's Take The E39 M5 is a favorite among BMW enthusiasts – and for good reason, as it boasts an elegant design, a thrilling, naturally aspirated V8, and a mandatory 6-speed manual transmission. This particular example is comes in an amazing color combination – Le Mans Blue with a two-tone black and silver interior – and it's mostly unmodified, aside from Dinan springs and Koni shocks and struts. Plus, it comes with a clean, accident-free Carfax report, for added peace of mind.
