I'd go for it. If it was a manual it'd be the ultimate, so you'll have to swap it once you get it. I dunno, it depends on how you read the carfax. Best case, that first owner traded it in to a dealership, they didn't want to deal with it, and they sold it at auction. That doesn't necessarily mean it was a drug dealer car and was involved in a shootout or something. My buddy works at a used dealer and they send tons of cars to the auction, especially if it's something that's not "high end" enough for their place, or if it's like an STi or something, they don't want to have to deal with the turbo warranty.
The other one, where it got repo'd, that would probably be where someone used it as collateral for their house, filed for bankruptcy, defaulted on the loan, etc. I dunno, I'm not an economics/banking expert, but those things aren't necessarily telling me that's it's abused. Used? sure, it's used.
Honestly, any car will have problems. It's about getting a car that you like well enough that you don't mind fixing the problems that it has and will develop. You might as well enjoy the car if it will be a large chunk of your life, or you'll spend time in it, it has special significance to you, etc.
