Kevin,
I agree it looks great and if it took 8 hours you can figure it out pretty easily. Around $70 per hour which would not surprise me today. They must have done this before because I have been told it can be pretty tricky. When I get my estimate which is promised for next Monday they are to quote doing the convertible top and the new headliner in the hardtop as a phase 2 quote. After reading all the replies from everyone I am expecting maybe a $5,000 installation number on the leather seats, carpet, doors, kick panels, dash, windlace, and the rest. If they quote the canvas roof and the headliner in the hardtop I am expecting another $1200. If it comes in better than that I will be pleasantly surprised. And this is in addition the the interior kit.
I think I am happier if I guess high and it comes in lower. OF course whatever quote they come in with I will offer the GREEN option (cash) and that usually gets another 10+%. But you never know. Time will tell.
Dick
