I'm also looking for a Mk5, but IMHO, prices are all over the place at the moment, as the dealers don't seem to be selling, and private cars are trying to be sold at trade prices!!!!!.
Its the end of the month, and the dealers will want to get their sale figures, so go and ask for ar least 10% off, and see what they say.There are plently of Mk5's out their.... AND be patient !!
Good luck
