Got a Nissan Altima Hybrid...
I have loved it. Has definitely cut my gas costs by ~35%. I bought an 07 model in 2008. The dealer was willing to negotiate. Also, 07 was the first year offered so I was nervous about any kinks they hadn't worked out but to date, no issues. Car is very roomy- except the trunk. The batteries take up a good portion, but still enough room for groceries etc... For me- was a great decision.. especially with the tax credit this year new buyers are entitled to.
