Good job Reaper. My first concern starts with the subject and in 1989 they did not title any black TC's. The blue grease that Reaper spoke of used on the pull down mechanism was also used in the odometer and when it harden over time broke the gears in the odometer and it no longer works. There was a total of 7,300 TC made so you can see how many spare parts are available except when one finds it way to the junk pile. I would not buy one without seeing and driving the car as there can be a lot of hidden problems. Check every moving part such as power seats, antenna, pull down, windows, door locks and so on. Mileage is a big consideration for pricing and when the mileage is lower the interior leather is probably in better condition. Good luck. They are a lot of fun driving.
