Is there a way to inspect (externally) if the transmission snap ring repair has been performed on an affected 91/92 NSX ? I think the trans housing has a new P/N (21200-PR8-000) but I don't know if it's easily visable. Many high mileage cars have owners who don't know. Also, are there any tips on what to look for before buying a high mileage (70 to 90K)early model NSX? Not the typical things, but items that are unique to the NSX and could result in expensive repair. Thanks, Mark911 (I'm a converted Porsche lover)
