get full coverage,, then burn it,, get new NSX, but if you dont wanna do that,, to give you a ball park of the price,, a timing belt and water pump install from the dealer will run you 2,800, the rear quarter panel is 2000 bucks, so with that said your looking at new transmission, 6-7K master clutch, pedal, etc. your looking at alot of work, and alot of parts, and Labor per hour pushes around 90-130 HR, so have fun with the automatic, if it has some Sentimental value keep it as is!! the previous owner would have wanted it that way! thats why they left it to you
