My advice for what it’s worth (not a lot :-)) is buy the best one you can afford, buying cheap and doing the work yourself almost inevitably costs more in the long run.
I'm well aware that you don't get back what you put in financially but half the fun of owning these cars is tinkering. Not to everyone's taste but I like to do a bit of spannering! But the price must reflect that some work needs doing!
