Now that my 2005 G6 GT Sedan is toast because some idiot was texting and driving, I thought I would post a thread for those looking for info on the G6.
First owner was a lease and never rust checked the vehicle. I was the second owner, purchased for $10,500 with 56,000km in Jan. 2009 and it died with 130,000km in Jan. 2013
Rust checked (Canada) each year I owned it, the body was in mint condition.
Oil changes every 5,000km
Air filter every 20,000km
Tires at 77,000km
Front/rear pads and rotars at 87,000km
Coolant flush at 87,000km (GM 5 year spec.)
Fuel system flush at 108,000km
Tie Rods at 121,000km
Front Stuts/rear shocks at 125,000km
Overall this was a good investment and turned out to be a very reliable car. I was so impressed with my 2005 G6 that I went and purchsed a 2006 G6 GT Coupe yesterday.
