I see it this way, the SVX is a big touring car, lots of fun and very refined inside and out. The STi is a fast very fun play car, fun off the line, on the dirt road, around little curvy roads, but on the interstate a noisy box with half the looks and not as smooth or refined. So ill just take one of each
If i had the money right now i would give up the SVX for one but that is cause i would love a little more power and such and a manual for sure. The SVX is one of the coolest cars ever and i will prolly always own one though.
