I had a BMW 750i up to 140+ and it wasn’t even breathing hard. It had 180 in it easy. But I didn’t.
That’s fast enough. Dads big Plymouth might have gone faster, but the speedo pegged at 140. It hit dips in the road pretty hard at that speed. I was 19 or so and didn’t know enough to be scared. I think dad might have been showing off a little.
