Thank you for this great article, and distracting me from my schoolwork. :D
Wow, ugly bastard but just wow.
John Lingenfelter must have some serious balls to take it to that speed.
Is it the extra body kit that makes it look like a Fiero on steroids? Or am I just forgetting how horrible looking the 80's vettes were?
the 80's vette's werent all that bad. that one in particular with that front looking like a mutant pig looks like crap. but thats just my opinion. the regular stock vette's tho werent all that bad. but still. thats insane...

Lingenfelter has big, big balls.

He died on a drag strip as well.

Over the course of a career that spanned more than four decades, Lingenfelter won in everything from Super Stock and Comp door cars to econo dragsters, Pro Stock Trucks, and NHRA Summit Sport Compact Drag Racing Series entries. he was the first Comp driver to break the six-second quarter-mile barrier, and in 2002, upon joining the NHRA Summit Sport Compact Drag Racing Series, he quickly became a force, winning one event and eventually piloting His Summit Racing-backed, Ecotec-powered Chevy Cavalier to the sport's first six-second pass by a fourcylinder-powered machine at that year's Mazda NHRA Sport Compact World Finals in Pomona. It was in that same car that Lingenfelter's glorious racing career ended a day after breaking the barrier.

While racing R.J. Simrock in the semifinals of the October event, Lingenfelter lost control of his Cavalier and crashed heavily. he lapsed into a coma during surgery in November 2002 and remained in a semi-comatose state until his death Dec. 25, 2003, at Adams County Memorial Hospital in Decatur, Ind. he was 58,

forget about the holes in the hood, i think it looks rather good, but then maybe im just excited to hear that the 254mph claim is actually true, for years i thought it was something a 10 year old typed on the internet and somehow regular people just believed it
