There is no more 330i and the 328i now has the 330i's 3.0 liter motor, despite the moniker. It's still a lot more $ than a similarly priced A3 2.0T and if you're gonna compare it to the 3.2Q, you have to use the 328xi as a comparison...closer there. The BMWs are a lot more used, that's for sure. I looked into getting a 04-05 330xi and they were in the mid to high 20s. I got an 06 A3 2.0T with Premium, sunroof and 65k miles (a lot of miles, I know, but a woman commuting) for $16.5k
