If the thought of driving a Vauxhall Senator only brings to mind that music from ITV's The Bill, then you've probably not driven one. These cars have to be one of the most under-rated vehicles on the used market and good late ones still fetch strong money.
Vauxhall's biggest car was never a huge seller, though its smaller-engined relation, the Carlton, enjoyed more success. In its seven-year lifetime, just over 30,000 examples of the second generation Senator were sold, so used examples are not exactly thick on the ground nowadays. But they're well worth seeking out for their effortless cruising ability and high luxury feature count.
