With your qualifications you should easily be able to build a buggy
and its always cheaper to do it your self.
my two cents is you build your buggy instead of buying one.
We can start on what style you like?
There are hundreds of differant body styles with esintialy the same chassie.
So find a body you like or go with the new body for starters
new bodys come from a couple places,
Closest to you would be Bearin buggys
we are lucky here in Texas with two body makers.
Texas Buggys as well as Hawkeye buggys both contributors to the site and dang good folks to boot (see sponsors page)
as the guys stated before chassies come in two tyles
old and new.
old chassies are VW based and will do fine for most street and trail riding
old chassies also can be broken down into swing axil or IRS
IRS is preferd for its handiling and ease of seting up its stance.
new chassies are being built by several folks right now including the above mentioned and can be built to do what ever you mind and pocket book can stand
a doner bug is recomended as it realy speeds up the parts hunt if you intened to buld a stock buggy.
DONT BUY A super Bettle MCpherson struts they are not for buggys
most beetle parts even after 40 years are in usable shape and can be cleaned up inspected and refurbished with new parts if required.
parts for VWs are readily available and quality depends on what you buy.
so that ought to give you and Idea of the next set of decisions that have to be made.
Once you get those down we can move forward.
Do your research on the net to help you make the decisions
some light reading is in order.
