    I have a 2007 ZO6 with 40000 mi. on it. I haven't experienced any obvious issue with the engine at this point; however, a local Corvette shop has recommended that I have the heads removed and examined to prevent the possibility of major damage to the engine. Is this a good idea? Does anyone...

    Extended Warranty for 2007 ZO6

    This is my first time posting a thread so, hopefully, I'm doing it correctly. When I bought my 2007 ZO6 in July I also bought an extended GM warranty ( 6yr. 48000mi. ) for about $1600.00. When GM began their 5yr. 100000mi. powertrain coverage I contacted them to see what adjustment they...
