|Comments:||the car is surprisingly well-balanced in cornering. I drive it to
work daily and it's very reliable. I'm preparing to spend the winter
giving it proper body and paint work. Future plans include a GM 671
supercharger, which will bump it up to nearly 900hp. My wife says:
"Not until I get my new living room furniture and drapes!" Rats!!!
