1988 BMW 535is/Euro M5 Conversion

$_57 (3)

Hagerty has this car listed under BMW E28 M5s, but its origin as a 525is and ensuing plethora of modifications make it a difficult car to classify. It recently received a Euro exterior conversion after a huge modification list of aftermarket E28 parts and OEM M5 parts, creating a FrankenE28 that is truly impressive. Bored and stroked S38s in any chassis are the stuff dreams are made of, with this custom build’s 350hp usurping even the almighty S38B38. A Wilwood big brake kit and Dinan/Koni/Bilstein suspension set up deviate from staying too true to the M5, but a full M5 interior and trunk, including battery relocation, are classy and expensive conversions. While not a fully dedicated M5 tribute/conversion, this ticks all the boxes in the outstanding E28 category.

The buyer will be responsible for all shipping costs but I will help coordinate pickup. The car will not be released until payment is received in full.

Professional appraised for $36,200.

The vehicle has a clean history report and there are over $110K in receipts and copies of all magazine publications are included for the next caretaker.

California Title in hand.

$110k in receipts is extreme, but thankfully the seller is quite reasonable and even undercutting his quoted appraisal. There’s no question that it would be a financial black hole to recreate any one of the modified areas, let alone the total package. My $32.5k would probably go to one of the pristine M5’s we’ve seen recently, but if you don’t care about the real M badge and just want a screaming E28, this is an incredible build.
