| We have had an 07 since new and are very satisfied with it. It has only been in the shop once for a check engine light, they fixed that, a front wheel bearing, and a relief valve in the oil gallery all under warranty. I don't know that the active fuel management gains that much, we get +15 mpg daily driving and +18 on the highway. 75k miles and works great. We plan on running her till she croaks, hope its a long time. When we run E85 in it it loses about 1.5 mpg daily driving, haven't run that on the open road yet. | |
