I am looking to purchase my first NSX and my budget puts me in the 91-92 model year range. I have heard alot about the infamous 'snap-ring' problem on early model NSX's. What I would like to know is this: does anyone have the VIN range or ranges and model years that were affected? Or if there is another way to figure it out that information would be welcome as well. Also, if there were any other problems that were prevalent on the early models, any advice would be appreciated.
