I drive all of my C's and all have been on long trips.
They were built and meant to be driven.
All 3 C's drove 754 miles one way to be at the FCBO show in Volo.
The Newport travelled to Carlisle and then to Washington. Then to Newfoundand.
Did 10k in one year without a hiccup
I always carry tools, spare ignition parts, a 2 ton trolley jack, chock if wood and a breaker bar with a 3/4 socket.
No fancy oils,, so I can top up with whatever is available to keep goIng.
.
In 3 months, Grace racked up over 3000 miles and is due for an oil change!
Ditto Frankie.
All have upgraded electrical systems for reliability.
Just stay on top of maitenance and repairs, and put Jesus on the dashboard!
