<BR>Impressions
<BR>
<BR>This car is a real sleeper. It ran a 12.718 @ 103.36mph with a 1.812 60' time in the 1/4 mile (with 26x6x15 slicks, no bumpers, Dellorto 45 DLRA carbs, no air cleaners, Sunoco Standard (Purple) race fuel, no fan belt and stinger instead of dual mufflers). It drives the boys in the pony cars crazy. It's very fast in a straight line and handles the curves like a sports car. The only drawback is that its noisy, but after all it was originally designed in the 1930's. The best thing is whoever you meet, they either had a Bug or have a story to tell. And the kids think its very cool.
