To get thread back on track. You need to ask yourself what you want from the car. Do you want something that needs lots of work, something that needs a little tidying up, or something you only have to do the routine maintenance on?
Then there is the question of use. Do you need/want performance or just to be able to enjoy a pleasant drive at moderate speeds.
I have a 13/60 which has no problem keeping up with traffic, and overtaking - ok so acceleration isn't breath taking. I get an enormous amount of pleasure from it, happily cruises at 90/100 kph. Will even do 130 if I let it!
