2007 Mercedes-Benz E-Class E63 AMG 4dr Sedan (6.2L 8cyl 7A)
I love driving this car! It feels faster than the Porsche Carrera S Cabriolet I traded in, it's infinitely more comfortable and it's capable of swallowing massive amounts of miles in a day. Take a road trip in one and you'll never want to fly (in the air) again.
The engine! 507 HP! It's fantastic! And, when on cruise control, it will return 22 mpg highway, not an econocar, but not a pig, either.
None. It's a spectacular certified pre- owned car, as the initial depreciation is rather daunting. After that, it's a spectacular automotive experience.
