1990 Porsche 928 S-4

Description

The good:  This 1990 Porsche 928S4, Linen-Grey Metallic exterior, with dark blue interior, has only 62,300 miles.  Interior is near perfect - no rips, cracks, or warping of any interior panels. All paint appears to be original factory paint.  The 5.0l v8 engine has a Stage 3 Murf Supercharger that made 500 WHP when originally tuned (I was there), but then was detuned to 475 WHP for longevity and drivability.  This car is FAST!  I've known this car for 10 years, and bought it from a friend about a year ago.  Of all the 928s I have owned over the years (10+), this is the nicest and cleanest one I have ever had. Since I owned it, I have charged the AC system (blows cold which is rare for a 928), fixed the AC relay in the head unit, replaced high-capacity fuel pump (Bosch 044), cleaned and replaced all injectors, new spark plugs, and serviced PSD (limited slip differential actuator) with fresh fluid.
The not-so good:  This 1990 928S4 only has a couple minor flaws. 1) there are a couple of paint chips on the front bumper and lower valance, 2).There is a small quarter-size paint bubble on the passenger aluminum door, 3) lower passenger rear speaker grill surround is missing, and driver side is cracked (common issue), 4) one of the wrenches in the tool kit is missing (12-13mm), 5) some paint flaked off around the drive-side rear-wheel center cap. 6) some of the stitching on the leather steering wheel has come off - I think some time with needle and thread would fix this as the leather appears to still be in-tact (not torn).
Things you should/want to know: 1). The timing belt is in good condition, but should be serviced in the next ~2 years. 2.) It appears the timing belt tensioner is weeping oil. 3.) Tires are from '09, but have lots of tread. 4). Wheels are aftermarket Cup 1 replicas - I do not have the original wheels.  5). Brakes have tons of pad left (~75%) 6). Car has a rear muffler bypass 'test pipe', and appears to have resonators from a 928 GT (smaller), but still retains original Catalytic converters.  7) Car has both factory belly pans, but front plastic one has some minor cracks - would suggest getting an aluminum pan at some point. 8) Vinyl covering on upper door panels is coming loose and should be re-glued. 9). Car has after-market radio (w/ bluetooth) and a 600W multi-channel amp occupies the rear spare-tire well. 10.) I only have one key for it, but at least it is the longer 'alarm' key - additional keys can be ordered out of Australia via photo
Car is located in Canton, Michigan, near Detroit Metro airport (DTW).  I drove this car to NC and back earlier this year for the annual Sharks in the Mountains event, and I would not hesitate flying in and driving it home.
Reason for selling: Daughter is going to med-school and I have another 928 that needs attention.
