For those of you who think 20 grand for an ultra low mileage GN is crazy, let me ask you this.
Would you pay $18,500 for a 2005 car that you know is gonna be a collectible, pay for it for up to 5 years, then store it for a total of 18 years (driving it less than 300 miles a year) if you knew you would only get $20,000 for it in 2023. Not me!!!
I think I did alright on my GN....sure I paid top dollar, but in reality I bought a practically brand new GN in 2005 for $700 more than it sold for in 1987. Given inflation, I paid way less than the original owner. It's all in what you are looking for....if you want a decent GN that is tweaked, they are a dime a dozen. If you want a practically new GN that nobody has molested, your gonna pay.....there aren't that many left.
