Accelerating to 80 was no worse then in my Saturn SL2. The cabin noise, thats another question, I can't really remember it all that well from the test drive. I'd guess though that again it was no worse then the Saturn I drive, since it doesn't stand out in my mind as a negative.

The only negative I had with the Prius was the dealership. Completly ignored at one, then the second, had a sales guy get all pissy with me including discussing economics when enquiring about the employee discount agreement between HP and Toyota. He also tried to steal the sale from the first sales guy I talked to, and was happy to deal with.

In the end, I decided I didn't need another car, and paying off my Saturn right now should be a priority, since the loan amount left is higher then bluebook by a bit.
