For the second year running, the highest placed Vauxhall is the Omega. And that will disappoint bosses, as fresher models languish below the ageing executive. According to owners, the Omega still has lots to offer as a used buy, and it netted two top 10 finishes. Seventh for ride quality and eighth for comfort prove the car’s credentials as a motorway cruiser. You also like the practicality and ease of driving, but the Omega’'s reliability record is poor and keeping it on the road can be costly.
