Wasn't going to say anything til the Bird brought it up but..... I have a Pontiac G6 (Impala Wannbe?) or the other way around? Thing is the Warden found it when I was prowling thru car lots. (Bad habit) and we ended up with it. Story here is it is a 4 banger. I was looking at it until we opened the hood on that 4 banger. I closed the hood and my words to her were " You've see enough! Forget it!!" The salesman then said "Just drive it. I felt the same as you about these 4 cylinders!" So we took it for a drive so she couldn't say I didn't give it a chance. Its still in our driveway!! That little thing is awlsome. And gets about 26-28 MPG with me and my foot driving it. Will run right with most V-6s. Not enough difference to write home about. My son ended up with a Bonnville V-6 about the same time and we both compared them. 4- Banger will shock you. V-6 does have more power but only if you got your foot thru the firewall. Other than that it is very hard to tell the difference. Got 70k on it already. I want to see how it handles 200k. Drive train is covered til 100k. It better not start acting up til past then, I could "Make" it blow and try to get a new one out of them??
