It's all cars and has been like this for a while, scrappage killed off a lot of the cheaper motors and the new haven't filtered down yet and quite simply there aren't as many people buying new cars now so less trickle down overall. The price for scrap has gone up and with the hassle and cost involved in getting an MOT (including garages wanting more money) on a car means that there aren't any £250 cars floating about any more (combine this with the new insurance/tax laws it complicates matters further still), the cheapest cars start around £500 for a banger so even a £500 repair on an old car is cost effective.
Saying that, there are some utter bargains about on used Saabs at the moment if you look about, just you need a few thousand quid to realise them.
