it is a 300d , not 300D . The engine is petrol , not Diesel ; the d indicates the fourth variation of the type and also that it has the extended wheelbase , hence the d suffix , which also made it a W189 ; this car has a extra quarter light completely separate from the rear door , with the rear seat set further back . Some models had additional 'jump seats' in the back ; others might have been fitted with drinks cabinets or anything else the buyer specified .
