Havn't see them at a bit over a £1k, seen them at about £3k. to £4k.
Might be dependent on the time of the year, but I remember watching Wheeler Dealers last year and they bought a boxster 3.2S for 1000quid which basically just needed a service. I remember thinking no way were they that cheap and so I looked online and sure enough there quite a few to choose from for £1500 or less, runners with MOT etc. However looking again quickly just now, you seem to be right, they are £3k->£4k, so maybe its because summers approaching, suns out and thats pushed the prices up slightly.
a grand?! find me one and I'll buy it.
the ash tray is worth more than that!
