I know it's difficult to roll a car over on it's top, because I've not accomplished it yet.
But, I'd never allow a person's first vehicle to be a convertible
just in case
in my experience, first vehicles have the highest percentage chance of being in a fender bender or worse accident
I'd lean towards something that doesn't cost too much to repair or replace
Like an 81 Dodge Omni or 1985 1/2 Ford Escort
