I trailered my ERA back to London in 06 and another member of Cascade Cobras and his wife drove their FFR back in (I think) 08. For both of us good weather on the way over and several days of rain on the way back.
London for Cobras is the equivalent of Sturgis for motorcycles although not as wild. A memorable experience.
If you're going to drive it make sure you have comfortable seats and pack your weather gear just in case.
Most memorable events were the cruise into London with a couple of hundred other cobras and the Main Street drags.
I recommend it to everyone who owns a Cobra if there's any way you can do it.
