I rented a Prius for a business trip as I get paid $37.5 cents per mile to use my own car. I rented the Prius for $32.00 a day, drove over 460 miles while getting a chance to try one out. The car had 6 miles on it when I rented it. I drove the highway at 65-75 mph and ran the car hard (rental). I noticed when climbing hills, the engine really winds up. No tachometer but must be over 4000 rpm? Does anyone know? For the trip, I got 41.1 mpg (math). When I got home, I had the gas station fill the tank until it spilled out on the paint. I then commuted for 4 days with the Pruis and then filled the tank the same way as before. It took 1.77 gallons to go 90 miles. Not bad. That comes out to be 50.847 mpg. I wanted to wait for the 2004 Prius as I read the car would have a more acceptable styling. After seeing the pictures, I like the old Prius much better. So maybe a 2003 Prius is in my future? I drive a luxury car right now (1993 Chrysler Imperial) that gets 18-19 commuting and 26-29 on the highway. The Prius would only be purchased to help save the planet as I would be giving up a lot not driving the Imperial.
