Here's my story , about 1-1/2 years ago a TB friend gave me a heads up on an X possibly going to be for sale near me . I had him get me the contact info for the guy . When I first talked to him he was very back and forth about selling it , but felt he should as he was 65 years old and had his fun with it , and if something happened to him , to not leave the burden on his family members of what to do with the car . This was Nov 14 , and after numerous phone conversations , he invited down to see it , regardless at that time I was not ready to act if he was to sell . I kept in contact with him frequently .This went on from Nov 14 to maybe April 15 .
Soon after the holidays , 2015 , I was ready to pull the trigger on an X , and approached him more seriously about his intentions with the car as I was a ready buyer if he was to sell . But , he was for a few weeks , was very reluctant about pulling the trigger himself .
So with that , I went and looked at 2 more to possibly buy , and both of them were not in my criteria of condition , not price , but condition , so I passed .
Not to get off track , but let this be a searching lesson for you , one of them was said HERE by at least 4 or 5 members to be the best thing since sliced bread , blah , blah , blah . As well as the seller putting it up on a high average . O.K , I was convinced , I drove 577 miles , 9 hours , to basically go buy it(money in my truck and all) , only to get there and have it be way over described by my standards . What a big let down !!!!!! Only to return home and the very next day , have the 65 year old guy , local one , 30 minutes from me , tell me his number and he was ready to sell !!!!!!
So the lesson I will live by , I don't care WHO tells me how nice something is , go se it for yourself before you buy it !!!!!!
So to answer your initial question , I guess it took me three to go look at , in about a 3 month span to finally own one . But I did search Ebay , TurboBuick , Carsonline , Hemmings , etc , etc dam near daily to see if any new ones popped up for sale .
Even since then I still pay attention to ones that come up for sale , and can honestly say , nothing yet has been attractive and comparable ( condition and price ) that I would have bought over the one I did buy .
What you have working against you now , is since the Toy Barn 362 X hammered for $150k at Barret-Jackson Palm Beach , and the 12 mile X from Mecum sell for $140k , now the lesser $$$$$$ , more miles GNX's are being asked higher than average as they were 1-2 years ago . Don't settle , be patient , keep on the lookout , and if one pops up in your criteria , don't hesitate , either get it done or pass .
Hope this helps , good luck with your search .
