Although I have no experience of others, I agree with the positive comments about the Xflow 4/4

Apart from 'engine out' stuff (core plug replace and 5sp gearbox transplant), all the work I've done has been completed outside on my front drive.
I've got a bit of welding to sort on the rear cross member, and some rot on the front wing which needs a fix, but again, all do-able on the drive.
Much like the MGB, it's a car for the car/mechanical enthusiast. If you are just in it for the driving experience I would suggest a later model may be better.
