I need some opinions here. On the for sale forum there was a 6000 mile GN that I was very interested in. Problem was it was undercoated so that turned me off to it. I've gathered some nice original TRs over the years but have always turned away from an undercoated car. This 6K mile car is just what I collect since it has great history, paperwork and it's basically a survivor. Tell me, should I not be so concerned about the undercoating? How much does it actually effect the value of the car? Thanks in advance for any thoughts
