I'm in the market for an 07 manual coupe. Here's my doubt: Z51 or no Z51. My only racing is onto/off freeways and an occasional burst for the thrill of it. I'm in the San Francisco Bay area and have generally undamaged, smooth roads on which to travel. I'm leaning towards buying the Z51 as I don't think the ride is too harsh and every review I've seen of the car is with the Z51 package and I'm worried the standard will lose some accelaration. Any thoughts? And how more pricey is the break service on a Z51? And do they rear wheels wear out sooner? Thanks much! |

I have the Z51 and really like it. The handling is excellent and the package features many upgraded components. The Supercar tires offer better dry road traction at the expense of some wet and cold performance. They do cost more and, particularly the rear tires, will wear faster. You can expect 15-20K for mileage depending on how you drive. The ride on the Z51 is stiffer than the other options, but not bad unless you routinely drive on very rough roads. Brake maintenance is not a real consideration. The manual transmission with the Z51 offers slightly more aggressive gearing, but acceleration is basically the same. Another option you might consider is the F55 magnetic ride suspension. For 2007 it will come with the same upgraded brakes and drilled rotors that the Z51 offers. You get your choice of ride stiffness, plus you can always add the Z51 sway bars to further enhance the handling. Even the base suspension will do a good job and can also be upgraded with the heavier sway bars. The car is a blast to drive. Whatever you wind up with, I'm sure you'll enjoy it. Stan |

I have an 05 C6 z51 convertible with a I think a unique problem. After driving the car with the AC off, the auto temp settings at 60,outside air open and fan on, when the engine is stopped even momentarily the air comming out the vents will climb to 110 degrees. I don't mean the initial hot rush of air all cars get when parked. I mean a climb to 110 and staying there until the car is parked overnight.The GM rep refuses to even look at the car. He said all cars do that.My first new car was purchased in 1966,a GTO convertible.I have had quite a few since then including a C5 convertible,and none have had this problem.To go Lemon Law will cost $6,000 with no recovery of legal fees. I just want the problem solved. HELP! Anyone have an answer or a simular problem?

| Thanks for the reply Stan but the AC was not in use only fresh outside air. Customer Service just refered the problem to the local rep who to repeat says this is normal.With an outside ambient temp of 75 degrees fahrenheit and the temp controls at 60 and the AC off no car should be blowing 110 degree air into the car. | |

A new wrinkle has been added to my over zealous cockpit heat problem. I called the GM customer service center for the 5th time, and again I was told the rep would not speak to me. I was advised to call the head of Roger Dean’s service dept. and make a new appointment. Rob McDonald argued with me while looking at a photography thermometer accurate to ¼ of a degree, that it was normal to have 120 degree heat blowing from the vents. All they did was fill out the paper work and send me home, a 50 mile trip. On the way home I turned off the AC and the temp started to climb to the ambient temp of 85. Then out of the blue I felt cool air coming out of the vents. The thermometer in the vent showed a temp of 78 and the cars sensor said an outside temp. of 85. Somehow with the AC physically turned off, you know line through the snow flake, the AC was on and running. There has to be a major computer problem when a car can turn on its AC while still turned off in the cockpit. Fotorich
