Hi all, I've owned BMW's and Audi's but never a Mercedes as yet, I've been trying to find a replacement for my current Audi S4 (B8) which I'd describe as a really gem in the Audi range, the 3.0 supercharged engine is really nice, they make around 350bhp as standard and are easily tuned, yet it still does high 20's in terms of MPG, not in the £500+ tax band and is very reliable with a 2010-2015 generation interior, all for £10-15k. I've had a scan through some of the Mercedes models and I saw that they make a CLS500 (the 2nd gen) which has a nice v8 with 400 bhp, probably tunable - yet they seem VERY rare, only 1 for sale on at and it's not far of Bmw F10 M5 money at £20k. Are there any models which fit into the below: - 2012 onwards/not too dated interior/exterior (Imo the 2ng gen CLS looks ace) - Mid size engine, i.e NOT a 4 pot (I hate the sound of them personally) so 3.0-4.5, i.e something which is going to be able to deliver 20+ mpg with normal mixed driving. I'm put off by big 5+ litre engines. - 350+ Bhp plus tunable, ideally would like 400+ - family friendly, i.e 4 door, suitable for toddlers. - sub £20k I'd love a C63 4.0 as I love the inside/outside looks, the engine seems a great sweet-spot of size vs power vs not crazy mpg, the size of the car is just right too, but they are still £27k+ as they aren't that old yet. The C43 looks nice, and I really like its AWD, but again is £24k+ as still quite new, plus you'd probably wish you got a c63 for that bit more power and drama of that engine. CLA45 - love the looks inside and out, nice size, but again it's a 4pot and I'd miss the power delivery of my current engine, even if the power is the same a supercharger is so smooth and the extra cylinders always count. I really cannot find much in this sub £20k bracket which is an improvement on the S4, seems a hard car to replace. I love it but naturally it feels a bit dated now, and it's never really been a looker, but the engine is great, the B&O stereo is fantastic and it's been bombproof.
