1957 BMW Isetta 300
Sold for: $57,200
Isettas are probably best known in the U.S. thanks to their association with television character Steve Urkel from the ’90s sitcom “Family Matters,” but as classic microcars gain traction in the marketplace, their values are on the rise. An outlier in the American-centric Staluppi collection, this Isetta 300 seats two and has a rear-mounted 0.3-liter engine. This was fair market value for a nicely restored car.
