2001 BMW M5 Sedan 4dr Sedan (4.9L 8cyl 6M)
Drive and you shall Believe
 Amazing power, yet very easy to handle. Ultimate luxury 4dr family car, very reliable, gas mileage is ok, what else do you expect? This really is a everyday drive to work/shop/trip car. Best of the e39 and my personal opinion, best bmw ever made. It does require oil adds between the 5k oil changes, since it is a very high compression engine. Don't care too much for the new shape or the interior, plus i enjoy changing gears myself. Best car i have ever owned in every manner. This is going to become a classic! If you can afford it, buy it! Don't compromise.
