1991 Mitsubishi Montero - 115mph (slightly downhill
)
1983 Datsun 280zx 2+2 - 138mph
1979 Chevy Camaro Z28 - 135mph
For the Datsun I had to use a gear calculator as the speedo only went up to 85mph
I hit that speed during a race with my buddy's Benz 280SE where we wanted to find out who had the faster 280. He said he maxed out at 135mph and I was walkin him the whole time so I guess its fairly accurate.
