Yeh I couldn't help but take a quick look and things didn't seem that bonkers unless, as you say, you get down to the low milers. But they were quite pricey before.To be fair that's probably over 100k miles now and will be worth between £10k and £15k tops depending on spec.
Its only low mileage 30k cars which are commanding £25k (if you are referring the to the E85 model with the best engine - S54)
