We bought our TCH 9/1/06. We made the purchase partly because of the tax credit and partly because of the hoped for MPG. As republicans, we didn't care about saving the planet.
Anyway, at our first service a month ago, we found out that Toyota had solved the chirping console with some new parts. Our sunroof was adjusted and that was about it.
When I drive it, I get about 36-7 MPG. My wife gets about 30. Technique matters with this car.
On the tax credit of "$2600", we ended up getting just over $2100 based on this year's returns. Enough to have justified the extra cost of the vehicle IMO.
Would I buy another? Ask me when gas hits $4-5 a gallon but yes, probably.
Oh, and we drove it rather than our RV to California (from Idaho) over spring vacation and found we could squeeze everything we needed for our family of four into that reduced size trunk. It was tight but it worked. BTW, our average MPG on that trip was just over 38 MPG and that included lots of interstate driving at 75 miles per hour.
