Yeah watch out with ebay, I bought my mk3 on there and was totally lied to.
Guy told me it was a 1989 supra, it seemed to fit the bill. However, turns out it was a 1986.5, with most of the body panels from some supra thats 1989+, and its got a engine from a 1987 supra. Not to mention the swap was done horribly, the SAFC2 didnt work right even though that was supposed to be one of the big selling points. He also told me how it had a walbro 255lph fuel pump which was a flat out lie, completly stock fuel pump. And also the interior is a mess.
But in the end, to fix all of these problems it cost me a little over $1000 so I guess it didnt all turn out bad.
I guess I rambled on there for a bit, but my answer to your question is, maybe its worth it, but MAKE SURE its as it seems first.
