All-wheel drive is available for an extra $2,300.
Whatever you call it, itâs a 1971 BMW 2500 sedan. I drove it home last week. It cost $2,800 and had been on Craigslist for months. Thatâs a long time, but then the previous owner lives high in the Sierras, more than an hour from anywhere, and the carâs interior appears to have been lived in by a pack of wolverines.
