Many luxury cars go to be used by the chauffeur market, where rear-seat comfort and entertainment are particularly important. For this reason, many models were specified with a 'rear seat package' (or similar) that sees two full-size rear seats fitted in the rear, instead of the usual three-seater bench.You can get luxury cars with five seats - useful if you're looking to use one of these vehicles as a family car, for example - but you might just have to search a bit harder.
