Selling a very rare 2006 BMW Z4 M Coupe with the S54 engine, less than 400 of these examples were produced in 2006. This vehicle has been completely refurbished inside and out. Our ASE Master BMW technician rebuilt this entire engine, includes replacement of problematic connecting rod bearings with VAC motorsports race bearing for the S54 engine, rebuilt the Vanos system, replaced all internal seals and gaskets including cylinder head gasket. No expense was spared on this rebuild. Thermostat and the entire cooling system was checked and all necessary parts were replaced. Engine also received and valve adjustment along with new spark plugs and air filters. This engine was then properly broken in. Fresh liqui moly race tech full synthetic gt1 10w60 oil was used. The refurbish did not stop there. Transmission was inspected and transmission oil was changed, new clutch, pressure plate and throw out bearing was installed. Rear differential was inspected and new synthetic gear oil was used. Vehicle also received new ABS control unit. Starter motor was also replaced for piece of mind. The interior received a professional detail and ozone treatment to make it look and smell like a new car. Last but not least brand new Continental tires were mounted and balanced, after that the Z4M coupe received a 4 wheel alignment. This Rare Z4M Coupe is as close to being brand new as it comes.
