wow, older thread brought back to life. lol.
i personally was looking at used mkiv supras for several months up until the release of the fr-s. although i'm quite partial to the supra, there were none in the $20k range that made me confident in spending my hard earned cash on. the gems are definitely still 30-50k in price. all the ones i checked out were obviously driven hard and modified at one point in time.
just compare these local listings from craigslist.

The more appealing one is definitely more expensive. The other two look like major work.
