I just signed up with Hagerty about 2 weeks ago, then I get their e-letter that surprised me that it featured the 89 TTA. Anyway, you can check it out at these links. (first leads to the article about 89 cars in general, but you can skip direct to the 2nd link below that refers to the TTA in specifics if you so desire)
