Went to see the car at the dealers today and all went very well, we were left alone to have a really good look at the car and the history which was nice, its never good to have the staff looking over your shoulder the whole time. Test drive proved that an impreza is certainly going to be the right car for me, was a lovely fun drive and not nearly as different from driving the golf than I'd expected, apart from the speed of course and the noise of the prodrive exhaust which was rather nice, not too loud.
Going to see a local car on a private sale tomorrow, mileage is a little more but it would be good to have a comparison.
