I used to always buy used cars and do all the maintenance and repair work myself. Then I bought a few new Toyotas and the only maintenance I did was the oil change and lube. Now I just don't have the time, I buy new cars only and usually buy another by the time the warranty expires, and all the maintenance is done by a dealer. One dealership (Their initials are Lustine Toyota) charges $80+ for regular maintenance on my Prius and 2 different dealers within a 45 minute drive (one is only 20 min) only charge $40.00 for the same maintenance, so all dealerships are definitely NOT the same, even with routine maintenance. Also, the Prius has different recommended air pressures for the front and rear tires...the expensive dealer doesn't adjust the pressure when they rotate the tires, but the cheaper ones both do. You lose somewhere between 2 and 5 mpg in gas mileage with the reversed air pressure.
