Hello all, new member here, but old GM product user. My household currently has 2 black Impala SSs ('04/'05 mine and son's) , '04 Diesel 2500HD crew cab for 5th wheel hauling, and my wife's '08 HHR SS with the great turbo 2.0L. I've done quite a few mods on my 3.8L S/C engine up to and including intercooling, but now has well over 150K miles (but still going strong).
My wife has told me now is the time, prior to her possible early retirement in a couple years, to get a new "fun" car. I love convertibles, I also have a couple of early 60s era Corvair 'verts in my stable (too much work to get running). My search landed me in G6 after deciding the Solstice was a bit small for my 6' 3" and lack of trunk space.
So, from what I've read, the 3.5L appears to be the better engine based on MPG and not much gain going to 3.9L performance wise, and a fairly big loss in MPG with the 3.0L. Opinions?
I like that Milzy Motorsports
has "some" performance stuff for this 3.5L engine. I also have HPtuners which I'm pretty sure handles the G6s (I just need more credits).
Any other buying advice? Like if you where to buy one again, you would get one with: X. For me that might be heated seats or the multi-speaker Monsoon system.
Thanks. Also member of HHR, GrandPrix (3.8L common engine to Impala), Impala forums (with same user name).
