Remember the Isetta, that funny little Italian micro car with a door on the front? They were built by several companies in several countries, including BMW in Germany. The BMW version had a BMW single cylinder, 12 HP four-stroke, 247 cc motorcycle engine. BMW’s 600 was a stretched version based on the Isetta, but had a 19 HP 582 cc flat twin as well as conventional doors and a back seat. The 700 evolved from there with a monocoque body in a rear engine configuration and the 30 HP R67 motorcycle engine. This coupe is listed on eBay with an opening bid of $1500, but no bids yet. It’s been sitting for decades and is a bit rusty.
The inside looks mostly complete. The gear knob is there but not the window crank or door handle. Some missing bits might be in the pile of included parts. Some new upholstery and a good cleaning would make this a nice interior.
There’s the 697 CC motorcycle 30 HP engine. It’s not seized. There was also sport version, the 700S with a pair of Solex carburetors and higher compression that had 40 HP. The 700S was raced and was very competitive in it’s class. Because of the popularity of vintage BMW motorcycles, parts for this engine should be available. There are also sites like oldtimereile that have lots of parts for the 700.
Here’s some of the rusty under bits. This will take some work. Is that a patch panel of some kind in the middle? It doesn’t appear to be welded into place. There is likely also rust hiding in other less obvious places.
Those fins look like they could be from the same sketch book as the Triumph Herald. This little car looks solid but has a long way to go to even be a driver. The coupes are less common than the sedans. It will be interesting to see what this one sells for. These little BMWs are almost rare, certainly uncommon, but so are the folks that appreciate them. Perhaps this will be restored to stock. It would be tempting to coax a little more than 30 horsepower out of that little BMW engine.
