I used swapalease this year to get rid of my 335 coupe (to make way for my 4.8 M-Sport). From a seller's perspective, it's fairly easy. I had 15 or so interested takers for my car (loaded, black/black, tint, in Chicago) and as was already stated, BMWFS made the process a snap.

WRT people not knowing how to lease, what's the difference? If you're in the market for a short term lease and the payments are right, what do you care if the original lessee is an idiot? There are tons of cars out on swapalease that have ludicriously low payments, likely because people put down huge cap cost reductions. So, you're getting the monthly benefit of their down payment without any of the cash outlay. I'm thinking about doing a short term on a convertible after I've seen how easy it was.
