Not as great as you would think. I averaged 33 mpg on the way to C-bus Friday. Around town my driving style wastes a lot of fuel Gas prices weren't really a factor in my decision to buy it. I was looking for the most car for the money and the Scion offers a lot for under 20 grand. I also looked at the new civic, GTI (nice!), mazda 3 and looked into leasing a luxury car like a 3 series, A4, C230 but my commute sucks up to many miles. I'm glad I bought in the end instead of leasing.
