Have to say my mates Impreza has been a total pain in the butt, he's on engine number 4 with it now. Several other friends have had Imprezas of different types and as far as I can remember all have blown at least one engine, It's totally put me off the cars. I can appreciate a nice Scoob still but wouldn't own one in a million years.
I've always thought the Mk5 Escort RS2000 was a very under rated car. 4k would see you with a very tidy car indeed and allow for a few choice mods into the bargain. MR2 turbo is a zippy little blighter if you can ignore the girlie/hairdresser image.
