When the average condition X1/9's cannot be found for under $4000 I will be willing to change my opinion. I can go on Craigslist right now and buy one of about 20 X's for under $4000, most being $2500 or less.
I'm betting on it. As soon as the new owner discovers the decay rate around the windshield area, it'll be re-posted.
Though the car is sold, no one really knows what the new buyer actually paid for it.
