Held back from replacing ML63 W164 as prices still tumbling. Could I ask in passing your MPG? In Central London I've been averaging between 5-8mpg. Assuming I can fill with 90 or so litres, I'm struggling to make it to the Wirral (215 miles) before empty. £120 tank of petrol to get there, another £120 tootling around up there and another £120 to get back to London. The train from London with 2 kids is £40 return. Often wonder about train there and rent a car at Lime Street.
