bought the model and colour i wanted, but only had a week (due to circumstances at the time) to find&buy one. looked at four and did travel some distance for each (furthest was a proper waste of time - real nause when people are 'economical with the truth' about a car's condition, esp. when the buyer's travelling).
one i bought was easily the nicest cosmetically, but has suffered with some mechanical probs - had less than 30k on the clock and i naively hoped it'd be good. they weren't faults i'd have been able to identify whilst looking at the car casually, but lesson learnt anyway.
