155 mph in 525i bmw myself.
Scariest ride along was at 108mph in a sand car at Glamis.
Were on long straight away from duners diner to cement flats.
The “trail” had sand whoops that made the ol king shocks earn their keep!
Terrified but loved every minute!
No for sale sign, I didn’t ask either, just admiring as you don’t see them anymore.
It’s in the big horn mountains, wyoming.
Can you give directions if you wanna track it down.
