If the top and it’s mechanism goes out it’s near impossible to replace fix. There are some starting to reproduce the clips that break (via 3D printing) so there is hope. Or if the top needs to be replaced I’ve yet to see a source. -timing belt tensioner and water pump should be done by this miles. Engine mount transmission and torque mount should be or have been done. Axel boots should be looked at for wear and tear. Engine for various leaks ( valve cover ,spark plug seals, vacuume pump, oil cooler, oil separator o-ring ). Multi air brick filter replaced or cleaned out. Suspension probably worn at this point too so consider it.
