people always look for a car with the lowest milage they can afford,
100% incorrect.
I think people, me included, look at other aspects first and foremost e.g colour, spec and price. When buying my M3, I knew I wanted a black one, then I wanted it to have certain things such as Sat nav & electric seats etc, then I narrowed those down into what I wanted to pay. Once I had whittled those cars down, only then did mileage come into it for me...........if your statement was true then people would be driving around in coloured cars that they despise because they bought the lowest milage cars they could afford.....
