Looking to buy as in you are already aware of grades and litre engines? Then it depends on your choice, 1.0 and 1.3 both are smooth and nice rides. There are some complains about its fuel economy but that varies on your driving styles. Remember it is a CVT transmission and some people may take longer to adjust themselves with the ride.
When it comes to owning something worth millions, one has to go through each and every details meaning check all visible nuts (hood, door, trunk, bumper housing) hinges and bolts for after market paint or signs of replacement. Pop the hood and start the car, get some glory of engine-sound at certain rpms. Check engine bay, headlights assembly, wiring condition. Get yourself on the ground at the front and back of car to check for any questionable matter. Have a deep feel of paint work (you need to have an eagle eye to point out the inconsistency). Read the auction documents, inspect the interior, have a ride over few pot holes or speed bumps. Check A/C or climate control. Tyre conditions, spare wheels? car jack? and others.
