@searay: Just so you're aware, your Gen8 'Bu warms the seats when started by remote. Gen7 models don't. (Except mine, but that's because I know how to tell it to do so.
@OP: I had an '09 2LT 3.6 V6 with "UltraLux" seats. As described above they have fake suede inserts and vinyl extensions. Mine were heated but only after I got in the car and turned the key on, then reached down and turn the heat on.
My '11 LTZ 3.6 V6 has leather seats (at least the inserts anyhow - not sure about the extensions). Seats are heated as well as the exterior mirrors (2LT didn't). Remote start does not heat the seats in stock configuration. I've modified mine by abandoning the ill-placed switches on the side of the seat and added rocker switches to the overhead console. Included in that mod is the ability to flip a switch so the seats warm during RVS.
I had 20,058 miles on my '09 when I traded it. I believe it had a little more power and economy than this one. I use the manual method to calculate my mpg's and regularly got over 30 on trips, with 18/20 in town in winter/summer.
My '11 has just over 33K on it now and at the same speeds and roads that I drove the '09 on I now get 27-29. Last November I drove 60 mph from home to Wash DC. I was able to get 503.5 miles on one tank and calculated my mpg at 36.4! Not usual because I normally drive speed limit plus 2-5 mph, but I was determined to see just how much I could squeeze out of it. On the return trip I drove "normal" speeds and got around 27-28 mpg.
When I had my '09 I was concerned because it was all black, inside and out, and I thought it might be unbearable in the summer. It wasn't, much to my surprise. I tinted both cars which might help. My '11 also doesn't seem to burn in summer or freeze too bad in winter, but now that I have warmed seats on RVS it really helps. The '11 is red with cocoa/cashmere interior (brown/tan to most folks
) and it looks really nice.
As far as engine maintenance goes, I agree with the above: use Dexos (synthetic blend) or full-synthetic oil, and don't let it go lots and lots of miles even if the OLM sez you can. Cheap insurance to get an oil change compared to the cost of a deductible on an extended warranty, the rental, etc. etc.
6-speed trannies through 2010 have paddle shifters on the steering wheel, for 2011 and 2012 they removed and added a single button to the shifter. I like the feel of the wheel better on long trips but like the paddles for manual shifting. Can't have my cake and eat it to, darn. If I had my drothers I'd like to see column-mounted paddles that don't interfere with the wheel and stay in on location relative to my hands instead of moving as the wheel turns. The shifts are slow and plodding, not like you would imagine for a manual shifter. It has to do with the programming, not the trans itself. The Camaro is a lot snappier, but I guess it should be.
