Bob, it sounds like a great offer.
BUT, luckily, Larry Svaton has been letting me drive (and occasionally wreck) his cars for the last several years. I don't even own a vehicle with a tow hitch!
Larry has two of these Caterhams. The one pictured there is the identically prepared sister car to Chris Fox's old car, which is how I got to talking to Randy when we were looking for some of her setup data.
I hope you can get Randy through that number. Good luck.
Rick
