20 years? Hah.Yur being too polite! We used good old 18th cenrtury
WAGON technology, Solid axles, lief springs, long perfected when Lincoln was
Prez! We HAD shitloads of Golf Cart springs we had to use up. Also it wasn't
gunna be a "Performance" car. We were never gunna scare Porsche, or EVen
Ford, with ride and handling!Having never met a Tropica I can't comment on
that.

"Lost Cord" SHOULD be required reading for ANYBODY thinking of going
into the Auto Biz! It is out of publication, but I think Bob Beaumont ran
more Publication runs?
