There are a lot of Teg's being imported at the moment which will drive prices down. Its already happening to the newer Teg DC5's. A 2001 plate DC5 used to be at least £12k a year ago, now can be had for less than £10k due to import companies flooding the market making them easy to get hold of.
I looked at several DC2's but decided against it, couldn't part with that sort of cash for a car that old!
Looking at your location, if you do think of getting one don't go to Dicksons of Dunblane, they are a bunch of over priced muppets.
