Passenger weight straining car?
No idea what it all weighed but we did 1000s of miles like that. I always thought, "Well, it's a Merc, it'll be OK."
And it was. Regular, 120 mph bursts and night-time dashes through the country.
I imagine a W124 series would be as good or better, assuming all the rubbery comfort stuff underneath is in good condition.
