Hello, I think about the purchase of a hardtop, because I drive my TT Roadster also in the winter. Unfortunately there is no more from AUDI, so a used one has to come. But before I buy one now at Ebay (or elsewhere) and it does not fit afterwards, I have the following questions to you: 1.)My TT (hydraulic cover operation) is built in 2004, so I will probably need a retrofit kit for the hardtop assembly. Is there still at AUDI, AUDI builds the one for me and what costs That’s about? 2.) Did there have different variants of the hardtop, or just one type? 3.)How are your experiences with the hardtop?Does that work, or can you do without it? I can’t think of more at the moment, just add your mustard, am grateful for every information, since I have no idea yet! Thanks already!!!
