This might be a trifle declasse, but I've happily driven a Model T Ford roadster since I was 14. The old motor was unrestored and very tired, but it could do an honest 40mph on level ground all day. The car handled beautifully at about 25-35mph. It could maybe do 45, but the brakes and steering definitely could not keep up at that speed.
In terms of handling, it is the most bicycle-like car you'll ever drive. Open Ts are amazingly nimble in gridlock--one time I drove through Los Angeles during rush hour--but they're the sort of car where you drive looking two signals ahead and drive defensively. They're also pretty reliable when sorted out, just most aren't. I also had a tired Model A coupe as a daily driver for a year, and I found the T easier and more enjoyable to drive, but the A is a night-and-day difference in terms of solidity.
