Looking at the MOT history I'd wonder, 7k miles on the last few years see if the bits (such as rear shocks or matching tyres per axle) have been changed for new.
This isn't a proper dealer with a showroom or even a car lot (I'm in Birmingham, I know where this says it is). It's just some space behind some shops.
