My hatch is doing pretty well heading for it's 10k service.
No engine worries. VERY few rattles (other than parcel shelf, which is sorted).
I've owned Blob, Classic (STI V1 so no plain jane) and the Hatch - the Hatch is the best all round car hands down. It's not been built entirely from a Japanese parts bin like some others.
It has PPP, Prodrive Springs and STI Quickshift - that sharpens up a lot of the "friendliness" of the standard hatch but is still a car that I can live with every day.
It is hugely more practical than any previous Impreza, has a rear wiper, cruise control and will do 30+mpg on a long motorway journey but still deliver blistering pace when needed at the switch of a button.
The hatch is easy to tune and tighten uop if you want it - suspension, brakes and every other bit that anybody remotely interested in on any other model changes anyway.
BUT
For the money I paid for mine, and the stuff fitted to it, it was a bargain compared to a mundane Mondeo etc which could be specced to the same price without the engineering. For a car circa £25k + new (average showroom price) it needs to be all things to all men to compete, as the Focus is, as the Golf R is (although that's VERY pricey).
I think it competes very well.
No matter what I buy next I certainly won't regret getting it and it has not let me down in any way (other than the usual thin paint issues).
My 2p/review after 9 months & 9000 miles of ownership.
