Tortoise as a pet - buy off gumtree?

[CoolHands]

Used to have one when we were kids - the ones you're not allowed now. Was always trying to escape.

My daughter aged 6 now wants one. So any thoughts / advice? I quite like them as a pet as not too much looking after. Cant have cats or dogs here. Goldfish are boring. Etc so thinking of Tortoise. Seems to be a couple of main breeds people advertise; don't want some special expensive breed just a regular one if there is such a thing. About a hundred quid seems to be the going rate.

can they live outside if you build a rabbit hutch type thing? With a fenced off running(!) area over part of the lawn.
