OH, now we are not going to be friends...lol.....time for a roadster....lol....but, they have been done...

TPMS...after awhile, will seem to have problems, dead batteries, sensors, whatever...I don't even look or notice the lights anymore...
I think you were talking about the hood support which is hydraulic....they do wear out over time...
Paint, well you did that...lol
What other problems are you having? You sure have driven it for awhile with that many road miles, so you must like it...
Back to the sunroof...keep in mind, you have that nice raised line that runs down the middle of the roof....putting a sunroof in, will break up that line and make the raised piece look funny to me...but, it is your car...never like sunroofs...lol...let us know what you need, and there is someone on here that can help....
