Since the first M5 of the ’80s, BMW has been known for making some of the best super sedans in the world. Seemingly with each generation, they get better. The E60 M5 was no different. With a V10 engine that sounded like their F1 power-plant, the E60 M5 was an instant hit. But despite having 400bhp, the legendary tuning minds at Dinan didn’t think it was enough. Which is why they went about releasing specialist engine components to up the ante. The car you see here has received the Dinan treatment: a headlining Dinan 5.8 Stroker kit. We’re assured that preventative maintenance has been carried out, and the car will be supplied with recent service history.
The exterior of this gray 2006 BMW M5 is largely stock, save for discrete Dinan badges on the rear. It features the M5 body kit and multi-spoke 19” alloy wheels but looks outwardly stock—a true advantage for those who prefer the understated sleeper look. The interior of the M5 looks to be in remarkable shape. This car comes with extended leather in black. It also features heated rear seats to ensure passengers stay warm during the winter months. This particular BMW M5 E60 features a head-up display, as well as a glass moonroof. It also has “Comfort Access”, which is BMW-speak for keyless entry—a rare convenience on a car this age.
This car underwent a Dinan conversion with 43,640 miles on the body. Included is the Dinan Stroker Kit, which increases the engine capacity from 5 liters to a whopping 5.8 liters. The conversion kit reportedly cost $30,000 new, and Dinan claimed a bump in power to 611 Whp and 468 lb-ft of torque. The motor comes with a certificate of authenticity from Dinan and includes a Dinan forged crankshaft, Dinan lightweight forged pistons, Dinan lightweight connecting rods and a Dinan serial-numbered block. It also comes with Dinan electronics and engine management software to keep everything in check, as well as a carbon cold-air intake from a BMW M6.
