Check out the 330
With the experience of the overnight 325 fresh in your mind, I'd suggest taking the 330 for a ride. The price difference is relatively small, but I think you'll be pleasantly shocked by the difference in the pickup between the two.
There's a significant boost in throttle response, low-end torque and braking power between the 325 and the 330. All for about $4,000 to $5,000.
It's the best way to sanity-check your experience with the 325. Just remind your self you don't want to have to go through this dilemma again, so I would suggest that you're best off getting the EXACT car you want this time out, no compromises. In the past, I've kicked myself for buying what was on the lot, and missing out on a feature I really missed later on.
