I think you're looking in the wrong places....
I got my 2007 S40 T5 just over a year ago with 86k miles, Custom plate, full Volvo service history, auto xenon headlights, auto rain wipers, Dolby Pro Logic II sound system, heated leather seats, bluetooth/phone, electric drivers seat and flip up child booster seats in the back - All for a grand total of £1900....It's manual too
Granted mine needed the belts/pulleys doing and had a boost problem which I knew how to sort. The guy had already got his new car so it was costing him money keeping it insured, I think he just wanted rid - I doubt I'd find anything again for that price, every time I check there are none for sale.
They're quite rare though, I've noticed the T5's seem to be creeping up in value. I wonder if it's due to Volvo dropping the T5 lump in favour of the 4 pots.
Maybe one day that'll be worth what the T5 R's are fetching these days...
