I raced one of these tonight. 0-55, I didnt punch it off the line, but I did after I saw he was going fast. By 55, he was at my back bumper. I dont know what kind of motor it was. the base 3.1 in these cars arent too bad for acceleration, my buddy test drove one last year. It certainly was a lot faster than the 3.1 in my mom's lumina. If it was the 3.1 motor, im happy, if it was the 3.4 im ecstatic! It looked just like this one, but it had the white lacy wheels instead of these 5 spoke ones
