I have to admit that I really like the new Civic Si. Everything except for that weird two teir instrument cluster. It looks really cheap and akward to my eyes.
Now the MK V GTi on the other hand is a bit slower, costs more, weighs more, gets worse milage and isn't going to be nearly as reliable but I think I would still be happier with it over the long haul. It just has that magic special something that I look for in a car. It just gets it right and it shows.
