Is your dad concerned about getting you a WRX or an STi? The two cars are rather different creatures. Allbeit the STi has no floor mats or stereo, that's a good thing and bad thing. I spent 10 bucks to get floor mats and I'm taking my sweet ass time getting my stereo put together. All though it's lonely and quiet inside the cabin, the drive is the best ever. Not a dull moment when I'm driving my STi. As for the WRX, it comes with a so-so stereo and the floormats are pretty tight. Any how, regardless of whichever one you pick, both of them are great automobiles.
