Hello everyone I am looking at purchasing Kellison SP1 with a top,  is there any type of market for these?  Just wondering?

You can keep an eye on the registry - http://www.dunebuggyarchives.com/registry/kellison -Looks like the last entry has a hard top and is located in Florida. The owner posted this from Jim Kellison:

Hi Dave,
We made over 3000 of the XP1s,but only sold about 40 of the hard tops for
them,so the hardtop is rare.

Someday I'll get around to finishing the site,including the Dune Buggies.

Best Regards
Jim
