Over the last year, I watched three different ones pop up on eBay. I was surprised in as much as so few were made. I don't believe any of them fetched over 2 grand or so. There's enough interchangabilty with later stuff that won't leave you stranded due to something breaking.
Personally, if it were a two door, I would LOVE one. Where is this one located?
