If you can keep the rust at bay, then a nice easy car to work on and I am sure a ready supply of spares available.
I had a 1964 MGB Roadster many years ago which was great fun and cheap to buy at the time, so I abused the hell out of it.
Thinking back it was fifty years ago (1975) and I paid £90 (three weeks wages) I think with insurance £80, not bad for a young hooligan, sold it for £50 with 12 months MOT.

Not sure if I would be able to get in and out easy these days though.
