That's a bit of a knee jerk reaction Roaldo
When you're looking at cars at that end of the spectrum things like length of MOT and service history make a big difference.
It also makes a bit of a difference where you are - if you're somewhere like London there's going to be dozens of cars like this which makes it a lot cheaper than if you're out in the sticks a bit more.
For that money though I'd expect a full years MOT possibly some tax thrown in and a history of service that makes me think I won't be at a garage in the next 2 weeks.
