I'm surprised that they park those outside in the heat and rain like that.
What I was saying is that I don't want to go buy a "new" car that has some hard miles on it. I want to put those hard miles on after the break in period.
Actually, they put one hard mile on the car after it rolls out of the assembly building. They have a one mile test circuit that every car is driven on prior to being moved to the shipping lot. The circuit has rumble strips that help them determine if everything is nice and tight, and a number of tight turns.
They also do a 0mph-100mph-0mph run. It is quite impressive. When I toured the plant in August of 1998 I was allowed to ride (encouraged actually) with one of the workers whose job it is to conduct these final inspection drives. We were talking Corvettes and before I knew it he asked if I wanted to drive the car around the circuit. The only thing I did not do was the 0mph-100mph-0mph test.
What I found out from this experence was that a car that is run on the test circuit, driven to the shipping area, loaded onto the trailer for delivery to the dealer, and PDIed at the dealer should have about 3 miles on the odometer.
I asked them rather discretely if the test circuit drive didn't run counter to the owner's manual "break-in" instructions which state no heavy braking for the first 200 miles, no full-throttle operation until 500 miles, etc., and they said no.
Some cars (I watched them perform this test on one) are rolled onto a chassis dynomometer. Steel barriers pop up from the floor in front of the front wheels, and a digital display folds down in front of the windshield. The worker climbs into the drivers seat and runs the car through the gears. The digital readouts must be within manufacturing tolerances or the car is pulled off to the side and apparently inspected further.
At one point in the assembly process, they asked if I wanted to start the engine for the first time on a black coupe that had just had all the fluid levels checked. Apparently they let a lot of people do this during tours.
If you are ever in the vicinity of Bowling Green, try and get there and take the tours which I believe happen twice a day. I was lucky in that I was back there (Fort Knox, about 110 miles north) for the 4th reunion of my regiment from Vietnam. One of the guys I served with in 1968 lives in Bowling Green and is friends with the plant manager. My buddy knows I am a Corvette fan so he arranged for the private tour. It was a good thing because when I arrived the UAW strike had just ended and they had suspended public tours. There were only four of us on the tour: My wife, me, my friend John, and his buddy.
The only negative is they do not allow cameras inside. That's too bad because they build the cars in color lots (it saves time cleaning the painting equipment between colors) and it is very photogenic (not to mention impressive ) to see 12 red Vettes, 12 black ones, etc., inching their way down the assembly line. There is one point where the assembled bodies are lowered onto the chassis (two separate lines actually merge here, the bodies coming down on top of the chassis).
The paint booth is also impressive. Robots do all the painting. All of the body panels are mounted on a jig and painted together so that there is consistency in the color, shade, and hue of each panel.
At the point where the wheels are mounted, a worker uses a very cool device to install all the lug nuts at once and torque them to the proper specification. Another device actually places the wheel and tire combination onto the studs very accurately and gently.
At every stage in the assembly process, great car is taken so that no marks are made on the painted surfaces. They put special mats on any part of the body where anything could come into contact with it and mar the finish.
All the workers we spoke to seemed to be very happy to be doing what they were doing and they all seemed to take great pride in talking about the Corvette.
A trip to the NCM is a must, although to be honest, it was rather disappointing. They may have added things since August of '98 so it may be more worthwhile now, I can't say. But the gift shop is cool. You can get practically everything conceivable with a Corvette logo on it.
Oh, the cars don't sit in the shipping area very long, I was told about a day, sometimes less, before they are loaded onto tractor-trailers for delivery to dealers. Corvettes do not travel by train as do most other GM vehicles.
I can certainly understand why they conduct these tours. It made me more likely to buy a Corvette and I'm reasonably certain it has the same effect on others.
