Tavarish’s recent Jalopnik post regarding the performance bargain available in the E39 540i solidified many of my car-brain’s transient thoughts. The 540i is a serious looker, with the E39’s grace and nearly all of the M5’s aggression. They are plentiful around the interwebs, but this example caught my eye with a host of Dinan upgrades, low mileage, and a 6-speed transmission. The Dinan supercharger pushes power slightly above the S62’s with plenty of drivetrain and chassis modifications to keep up. It may not quite trigger that special ///M response, but it will get you 99% of the way there while costing half of what a similar M5 would. At just over $10k, you’ll be hard pressed to find more performance per dollar, let alone in a car that looks this good.
