as kahn said the alfa has to be on the list to drive, i was poking around one the week really nicely kitted and seemed to well screwed together the one local to me i think has 16-17k on the clock leather etc and was only £13k
Only worries is, the alfa 147 is an old car now, and alfa are probably worse than SEAT when it comes to dealers

But the engine should be solid, its the same lump they use in the Astra, so 200+ bhp should be no problem.
