Depends on the manufacturer and the dealer. They all have different requirements and incentives. Try to find a local dealer that does decent volume with the TT manufacturer of your choice in order to get the best deal. Then do the same thing at another dealer and see which one offers the best deal. It takes a little leg work, but if you like to save some money then its well worth it.
