“I
believe the E-Type Jaguar is the most
beautiful car ever made. I bought my
first E-Type, a 1972 V-12 roadster, in 1985,
and I had no intention of doing anything
to it. I joined the Jaguar Club [of North
America], and a few years later, they started
a slalom program. I started driving in that
program, and began thinking about SCCA
events. Stew was maintaining my original
car, and we decided that it would be fun
to have a car that would do really well in
these events. I didn’t want to further modify
my near-stock car, so we started with a 1973
roadster to make The Beast.
“This car is clearly pretty potent on the
track, and Stew’s wife, Karen, has turned the
best time ever in a Jag, beating the previ-
ous best time by a half-second. Bob Hebert
drives for Donovan [Motorcar Service in
Lenox, Massachusetts], and he’s turned a
58-second lap in The Beast at Lime Rock. He
comes back with good feedback for Stew…
tweak the torsion bars, lower the tire pres-
sure… and as long as Karen’s autocrossing
it, Stew trucks it around for me. I can’t turn
those times at Lime Rock, so it’s great to
see what the car is able to do at the hands
of a good driver. I’ve hired Bob Hebert as
a coach, and I’m planning to continue to
do more track driving and probably get my
competition license.”
