Nah, too much money.
Here's the problem:
You could go two ways with it:
1.) Spend even more money to restore it to like new. At that point it would be foolish to drive it. So, now you've got a museum piece. I guess if you have the space and money, it might be a good long term investment.
2.) Don't restore, just drive it. Now you've spent $14,000 on an Explorer that you could recreate (ok, not exactly, as you can't get the exact Saleen body pieces- another reason not to drive it) for a LOT less.
3.) From what I've heard, if you call Saleen for any info on these, they'll pretend that they never even existed. There isn't even anything about them on the Saleen website. The history of Saleen pretty much ignores these Explorers. Granted, they were a very limited production, but it's almost like Saleen is embarrassed to be associated with them. So, kinda loses some of it's "shine" there. It would also make it hard to verfiy anything about the truck and/or the guys paperwork.
