Trying to help my ma buy a car. She has 6 grand to spend. Wants something 3-4 years old, not as big as the Rover estate she had but bigger than a small car. Reasonably roomy/eco/easy to drive. I have a giant auction house (like 5 Car sales a week, Arnold Clark, guys like that) near me.
I have a spectacularly poor knowledge of modern cars. Any good cars I should be looking at? Could I risk an auction? Any major pitfalls in buying in general?
Thanks in advance for any help.
