hey, I'm driving my 59 as a daily driver. it is just fine. drove it 8 hrs a few weeks ago, trailering a 1950 Buick, on I20. no problem. used to live in Austin, got it on I35 all the time, and ATX traffic is crazy
you'll probably need to change your maintenance routine a bit, and it'd be smart to get a little stock of part. some things are specialty only (as in, not Autozone, NAPA, ..). you know, get a few oil filters, pulley, points, condenser, some plumbing stuff (oil filter if you have one, fuel filter, carb rebuilding kit, a little more)
and then DRIVE THAT TRUCK
