Just keep your foot outta the boost and your SSEi is pretty much an N/A 3800(SE, SLE), am I thinking about this correctly? Im knocking down more than what my sticker said for MPG in town. Just checked it. (21MPG) Arnt the EPA estimates just calculated by a computer barring weight vs. HP? If you are honestly worried about MPG get a friggin' hybrid. Plus you'll get a tax write off. 94 GMC YUKON was my last vehicle (15MPG highway
) So, right now Im happy as a clam with my Bonne. Just get a bonne, you wont regret it!!!!
