BMW E63/E64 6 Series

Introduced for the 2004 model year, the E63 coupe and E64 convertible 6 Series resurrected BMW's grand tourer nameplate after a 14-year absence. The design, led by Chris Bangle, was controversial at the time for its unconventional lines and trunk lid, but it has since found an audience that appreciates its unique presence. The lineup was powered primarily by the N62 V8 engine, first as the 4.4L in the 645Ci and later as the 4.8L in the 650i, offering a blend of smooth power and a great exhaust note.

The market for the non-M 6 Series is driven by its compelling value. For a modest investment, buyers get a comfortable, fast, and well-equipped GT that still feels modern. While the V10-powered M6 occupies a different performance and price bracket, the 645Ci and 650i are appreciated for being more reliable and easier to live with daily. As these cars have fully depreciated, they now represent a stable buy for enthusiasts seeking style and performance on a budget.

With an average sale price around $15,000, the E63/E64 is one of the best performance bargains available. The wide price spread from under $2,000 to over $40,000 is almost entirely dependent on maintenance history, mileage, and condition. Well-cared-for, low-mileage examples, especially post-LCI 650i convertibles, command the highest prices, while neglected cars can be found for very little. Prospective buyers should budget for significant maintenance, as deferred repairs can quickly erase any initial savings.

Prices range from under $2,000 for project cars to over $40,000 for pristine, low-mileage examples.
