I too have one of those "old stories" about a car that was faster than spit. I had a 63 Austin-Healy 300 MKIII, red with red leather interior, wire wheels and an electric overdrive on the dash. 4 speed with a 6 cyl. Healy engine with 3 1 1/2" SU Carbs that I tuned to perfection. The exhast note was incredible and it drive like the wind.
At the time I lived in Providence, RI and used to hang up at college hill. All the kids from Brown and RISD used to have thier MGB's and some lotus europa's were around. I never took on more than I could chew but I could drive my butt off and beat many an MGB up the hill. Granted I could only get up to 3rd gear but I left them in the dust. I was never beaten and I raced some mustangs and some GTO's. Apexing the corners and driving it like I stole it. Did the same at Roger Williams Park, at night. Just that 6 cyl. with the SU's and 30 weight oil in the dampers made it all work.
And Yes!!! I race my Xfire at every opportunity, blow people away with speed and handling.
Our cars are world class, don't let anyone tell you any different.
