Maybe he's the brother of the dude trying to sell his RA23 for over 20-grand.
Yanno, this has got me thinking.... I'm wondering if these guys have trolled some of the forums, like Toymods and others, and seen how there are a lot of people wanting these old cars (especially if in good condition) and how some people drool over GT/GTVs etc and decided to play on that and whack up a big price on their cars.
I see it happen a lot on the Classic Computing Forums where people bump up the price on some old, though classic, computer. Some people fall for it and pay, others just think the seller is dreaming.
