That's a sweet ride. What do you estimate it's going to cost once the interior has been done? Total cost for the daily driver? It's really amazing how nice a car you can get these days for less than one years payments on a new one. There seems to be a lot of parts still available too for the E28 compared with the E24. Makes me wonder about making the switch. A nice 535is like yours would be an equal trade for my 635 CSi.
