2008 e60 M5 NEW ENGINE!!!!!!!!!!!!!!!!!

2008 e60 M5. General info below:
-Exterior: 9.5/10-Interior: 10/10-75,xxx miles-5.0L V10 engine-7 speed SMG III transmission-Registration valid until January 2018

I originally purchased the M5 knowing that the engine wasn't in the best of shape (ran rough, knocking, etc), so I took it to Castro Motorsport, a reputable shop with a long track record (North Hollywood, CA). The issue was initially identified as being VANOS-related, so we went ahead and replaced all four VANOS solenoids. Unfortunately, this didn't fix everything, and we soon found out that bad rod bearings had taken a devastating toll on the engine (as I had initially suspected). With few options remaining, I decided to go through with a complete engine rebuild. In addition to machining both cylinder heads, the following parts were replaced (brand new OEM):
-Crankshaft-Camshafts (on national back-order, imported from BMW Germany)-Pistons & O-Rings-Valves & Lifters-Rod bearings-VANOS assembly-VANOS oil pump-VANOS gearbox-VANOS solenoids-Coil packs-Spark plugs-Water pump-Engine mounts-All belts, pulleys, filters, etc-All cooling hoses, fluids, etc
We also inspected the entire drive train while it was out. We refilled all fluids and replaced anything else that looked sub-par, such as the clutch pressure plate, etc. Upon physical completion of the rebuild, the car was taken to Gintani (Van Nuys, California) for tuning and final touches (currently in the process of scheduling a dyno session). One more trip to Castro for some custom exhaust work, and the M5 was finally ready to go. I was given specific break-in instructions, which I have just recently finished by reaching 2,000 miles on the new engine. Though it pains me to do so, I'm selling the car because I need to free up some additional funds for a business project. The rebuild comes with a 1 year/12k mile warranty from Castro Motorsport. Additionally, all of the above-mentioned parts come with a 3-year warranty from Beverly Hills BMW. I have receipts for all parts and labor; these will be given to the new owner.
Now, for the bad part. Since the engine was giving the previous owner so many problems, he ended up lemon-ing it. The M5 now holds a salvage title. Though I am aware of the fact that this hurts the car's value, I'm hoping that potential buyers find solace in knowing that this car is in great condition. I'm certain that it'll be an absolute pleasure to drive for many, many miles to come.
Asking price is $23000
