I've been looking for the past several months and I don't see the prices coming down. Right now there are a few on Autotrader and they commanding the same prices they were 5/6 months ago, some higher than I've ever seen.
Because production numbers were so small, I think that the prices have bottomed. They might even start to go back up a bit.
