I have the first TT every produced. It was produced in January of 1990. It was built for a Yankee baseball player. I can't remember his name. It has fabric upholstery and manual driver seat adjustments. It also does not have climate control. It has a number 1 with a circle around it painted on the drivers side fender well under the hood. The VIN number verifies it is a TT. Should I continue to drive it or should I garage it?
