I'm a total newbie about Prii. I'm looking at a 2004 prius with Hymotion installed - not sure which model, I can find out. The dealer wants $12,000 US. It has 58K miles on it, looks in good shape. I drove it for 20 minutes and the monitor said I got 50.3 mpg. The dealer said he had not charged the Hymotion, but would for the next test drive. I noticed that the tires were more worn on the outside than the inside. Car rode perfectly. Also - major issue - this car is a salvage from Rhode Island. They had huge rains a few months back. The dealer has a very good reputation around here so I trust him as to how far the water came up, but it obviously would kill the resale value when/if I sell. Plus I won't be able to get normal financing, and I'm not sure about insurance. I understand I should find out if the suspension has been beefed up when the Hymotion was installed. Anything else I should be asking?
