fastest i went in a car was 115 or so in a Honda Accord v6 coupe. i didn't push that hard either. but the fastest i've ever gone was when i was a passenger in wlkngplygrnds Accord v6. we went 125 WITH four people in the car and a trunk FULL of amps on a long straight shoulderless stretch of the PA turnpike.
yes . . . yes we did . . . it was exceedingly smooth . . . PS I love my mistress
