The last time I bought a car, I thought I was pretty well-informed by reading from sites like Edmunds.com and KelleyBlueBook.com (both have the obligatory Ten Steps to Buying a New Car: here and here). I read the buying guides, collected the data, and learned all my lines before the day of the big showdown at the dealership. But that was all years ago (way back in 2000), and the web just gets richer and denser every year. These days if you want to buy a car, you shouldn’t miss CarBuyingTips.com. The guy behind the site is clearly obsessive… obsessive in a way that’s good for you. I can’t vouch for his personal happiness, but he can sure do you some good.
