I have a 2009 CLS 320CDI, which I love driving, but the need for a more practical car beckons. I hired a 2019 E220d estate not long ago, it wasn't too far off the pace of my 320 tbh and it was very economical 60mpg + which is a good 50% more than the 320, but the sound was nothing to write home about, though they seemed to have made the 4 cylinder diesel a lot less agricultural than before. It felt light on its feet too, though the cabin looks like a throwback from the 80s with the neons etc. The amount of money I (could) be spending opens up a whole carnucopia (deliberate spelling) of cars, including the 6.2L and 5.5L E63. I'm sure it'll be a struggle to get much more than 50% mpg compared with my old 320, though that sound ! I could go older and start looking at E55 too. I know the cars I've listed are poles apart, but I'm torn between being sensible and why the hell not !? Plus I've never driven a V8 before. Any thoughts on reliability, cost to run etc? I'm getting on a bit, so insurance isn't a problem. Milage-wise, I'll be doing 12k Miles a year ish. Thanks muchly.
