First I have a Subaru Outback Wagon. Aside from the problems That they fixed after a lawsuit, it is an awsome vehicle in the snow. The all wheel drive (one wheel at a time and don't let the salesman tell you any different) feature saved my life more than a few times. It will walk up a steep slippery hill. The Forester is pretty much the same car with a different interior. I find that most factory tuners suck while the tape or cd players are better.

My Impalla came with a separate amp in the trunk but the factory speakers suck. I replaced them with MB Quart speakers and it now kicks nicely. The only setback is that the Impala and lots of other newer cars have all the controls and security settings(alarm) wired thru the radio. If you replace it your screwed.

Good luck picking a new car!
