In 1988, Citation Motors, a BMW Dealership in Ontario, shut its doors with little explanation. The simple answer seems to be that the dealership had its concession license revoked, but nobody seems to be able to track down why exactly. Endras BMW, another Toronto-based Bimmer peddler, did some digging, but didn't come up with too much.
Whatever the case, the dealership moved to Toronto, switched its name to Downtown BMW, and went under in 2002. The owner of both places seems to be eccentric at best, as he left Citation where it sat, untouched, with a then-brand new 635csi and E28 5 Series abandoned inside. The business is reportedly well cared for, and the cars have not succumbed to the elements the way they would have were they truly left to rot.
The owner of the establishment apparently has little interest in selling the business or his wares. To make things more interesting, there's apparently an as-yet unopened underground storage facility and a back lot packed with junked Bimmers.
