I've been driving my 53 all over northern California. City,freeways, 110 degrees no problem. It is bone stock and no third brake light. I ride motorcycles a lot too and I figure it to be about the same. Just drive it and pay attention because nobody else is. If you are planning on going 80, zipping in and out of traffic and doing panic stops all day, just stick with a modern car. If you're looking to have a nice reliable cruiser, overdrive tranny, front discs and a rear end swap should get you comfortable on the highway. I'm not sure what is available for your motor but dual carbs and dual exhaust couldn't hurt in the power department. Good luck and how about a picture of your car?
