Land Cruisers aren’t/weren’t built for top end speed. Where they ‘shine’ is off-road in 4 Low!
Yours looks like a 60 Series? Nice rig!
My 80 series will still top 100 mph, but it takes a while to get there.
One thing about Land Cruisers…they will still be on the road when a lot of lesser vehicles are sitting in junk yards.
