not much difference, but it depends on the options
I own a 2005 Prius with 35K miles. I have the model with everything except the NAV options. It has the side curtain airbags, VSC, fog lamps, etc. The big difference is your color choices and I think a little chrome on the grill.
The car is still performing like new and in the warm months we are averaging 55-56 mpg 50/50 city hwy.
I'm looking at an '05 too
I also found an '05 for sale near me and an thinking about it. My main concern is it has over 61k miles on it. Does anyone think that is too much to dive into with that model year?
