I owned a 2006 Prius for 10 years before purchasing my 2015 Prius Three. My 2006 had 49,500 miles on it when I traded it in and was an excellent car to own. So far my new 2015 Prius Three has met all my expectations and I am very pleased with my purchase.
Dependability. Periodic ordinary maintenance, that's it. Brakes lasted well over 100,000 on my '02, so did the plugs. Quiet, smooth, and I am getting 55 mpg with my '11 Prius. Exceptional rear seat legroom and overall comfort. My '02 will still be on the road, except it was clobbered and totalled. I had 164k on it, and no question it would have made 250k. ore more. Only needed a waterpump after 150k. Amazing performance by A/C even after 15 years on the road, didn't burn a drop of oil, engine was very peppy for a 1.4 liter, and 50+ MPG was easy to attain. Drove cross country 4 times with no issues whatsoever, and it cruised smoothly at 70-80 MPH. At those speeds, mpg was 40-45, which I still considered outstanding. We have a '13 also.
Aside from the great gas mileage, there are more reasons to buy this car: 1: it's deceivingly roomy! I have long legs and so my seat goes all the way back. There is still plenty of leg room for a grown adult in the back. And all the seats are very comfortable. 2: the back storage area is very large - I can put all of my work tools and cases back there without sacrificing any passenger room. As I said earlier, these cars are deceptively roomy inside. 3: the electronics in this car are top notch. In my opinion, no other car maker does blue tooth systems better than Toyota. My iPhone works flawlessly in this car. Best car I ever bought.
