1989 BMW 535i Dinan Turbo, (Alpina B10 Bi-Turbo, E34 M5)

A great piece of BMW history. From what I've gathered this is 1 of 15 and 5 of those were automatic. 77xxx miles. I have owned the car 7 years and now have 3 kids under 4 years old. It is no longer practical and taking up much needed space.
Known as the "Delaware" car it was shipped to the Dinan shop in California and had an intercooled turbo, upgraded suspension, brakes, upgraded Dinan exhaust, Dinan 3 vdo gauge(oil temp, boost/vac, volt) panel, Dinan turbotronic computers, Dinan floor mats, safegaurd knock detector system all installed and was shipped back to DE. The wheels are Hartge Type A wrapped in Riken radials. The wheels were reconditioned, and the tires are less than 2,000 miles old.
The car was given to a previous owner by his wealthy developer boss. After many years it went into the same performance shop it was maintained at in DE for a leaking head gasket and leaking tranny. Once given the estimate the owner couldn’t afford to repair it and sold it to the owner of the shop. The shop owner had the HG repaired complete with 3 angle valve job, rebuilt the tranny and stored it driving it on occasion. When the transmission was rebuilt (<2,000 miles ago) the converter was loosened (3,000 rpm stall) and a shift kit was installed. During this time the speedo was replaced. There is a validation sticker on the door.
In his care the engine had been completely gone over including new belts, upgrading the injectors and a new fuel regulator was installed.
It’s been adult owned, stored in garage all its life and well maintained. It has had one repaint. IMO the paint is very good. No clear coat cracks but not perfect as there are some small dings here and there. There was an old cell phone mounted in the car and a couple small holes remain from the mounting bracket in the passenger foot well. That said this may be the cleanest of all of these on the road.
I've had dozens of internet tire kickers and numerous no shows over the past so don't waste our time...potential buyers with poor feedback will be ignored (I can read). Yes, the car is very fast, yes it is in very good shape, yes, I will schedule a visit.
