I traded in my old Pontiac Grand Am today and purchased a used 2012 Prius Four! I love the upgrade!! Any tips that I might want to keep in mind as I transition?
Start out by driving it like any other car, read up on hypermileing if you want to maximize mileage, and keep up with the scheduled maintenance. If you want to you can experiment with tire pressures (always 2 lbs more in front) to help with mileage, the tradeoff with higher tire pressures is a firmer ride, pick what works for you, enjoy.
