New shape M6 or 640d as a daily driver?
Discussion
The PCP on my C63 AMG ends in September and I'm wondering what to replace it with. I need to be able to cover 10-15k pa and having occasional use of 4 seats would be handy. I thought I'd settled on a 640d, which really impressed me on a test drive, but am wondering whether I'd find it a bit dull after the C63 and my previous work cars (AMV8, XKR, SLK55, M3...) I think the M6 looks far better (partly because of the more interesting colours available!)and the reviews I have found on line look positive. The fuel economy would be a big bonus with the 640d, but then not many of my daily cars have managed more than 20mpg so this isn't a major concern. I am considering buying secondhand this time - decent low miles 640d seem to be around low £30k, M6 around £22k more. Which would you recommend? My mileage is a mixture of Mway, and fast a and B roads and I am an enthusiastic driver - but not on it the whole time and this would only be used for work as I am lucky enough to have other toys too 
My M6 GC CP averages "Out of town " driving 24 MPG, the 640D gave 40MPG.
It is your choice but you may get bored with the Diesel.
On the other hand the M6 rarely gets to stretch it's legs, it's just too quick.
Depends were you live, how many "Old Bill" hiding up lay-bys as to how often you open the car out.
Good luck with your choice , the Comp Pack cars are much better all round IMO.

The M6 all day long if you are only doing that sort of mileage, we are doing around 35k to 40k miles a year at the moment in the 640d and its doing around 41mpg which is good for the performance it offers and I like most things about the 640d apart from the engine.
So for me the 6 series with a nice petrol engine under the bonnet would make a stunning package and a diesel engine is only ever used as a tool to cover long distances at a cheaper cost and for driving enjoyment and pleasure petrol is the only way to go.
Admitted some buy diesel because of its usable low down torque in daily driving but the M6 has that in abundance anyway, 313bhp or 560bhp...its a no brainer!!

I was following a 640D today and I was very, very surprised at the performance he had.
No doubt the M5 (so read as M6) got past him but that diesel engine is a bloody gem and to have that performance and MPG is undoubtedly the best of all worlds.
That said, I'm hoping to have an M6 after my M5 - you just can't beat an M

Given your previous cars you're used to something that's a little bit special - so the decision is a no brainer, M6. Unless you're looking to save money on fuel or depreciation.
I've bought "standard" cars but all always found them boring quickly and I ended up trading it in for performance car. So it cost me more money in the end.
If you can afford it, go for the M6. It will feel so much more special.

Thanks for all your replies I agree with those that think I would enjoy something a little more special than the 640d (however good a car that is) and for the same reason don't think a 650i would give me enough of an advantage over the 640d. So I intend to test drive an M6 at the weekend

If you bought one, would you be wondering what if you had bought the other?
So, if you bought a 640d (nice as it is), I think you would always be thinking what if I had gone for the M?
If you bought the M, I don't think you would wonder about the 640d anything like as often - maybe only when you were totting up fuel receipts...

Yes, good point. The alleged fuel economy of the M6 is still far better than I get from the C63, and better than the AMV8, XKR etc... so for me at least it could still be a relief! What sort of mpg do you get in the real world in an M6? If you bought one, would you be wondering what if you had bought the other?

My friend has seen 35mpg from his M5 on a long steady cruise on the M1 from Sheffield to London.
Considering the performance on tap that is awesome. The M6 might be even better being the slippier car.
Even with the lightest foot on a decent I have no managed anything better than 25mpg.Considering the performance on tap that is awesome. The M6 might be even better being the slippier car.

I got 28mpg yesterday driving on a mix of urban and motorway 180 miles in total 25miles urban and the rest on the M1, the 50mph zones help consumption.
35mpg seems a bit optimistic.
Rather sadly I have an app to track my expenditure (simply out of interest!) and have done so on my last three four cars and it's as accurate as you can get calculating mpg - the best I've ever recorded is 28.57 on a long run with the kids driving like an old fart.35mpg seems a bit optimistic.
I'd suggest there's no chance of 35mpg unless you simply sat there with the engine idling and not moving.

I drove to Newcastle in mine last night. I probably got 35mpg between London and Sheffield because at least half the journey (in time terms) was spent under Specs cameras at 50mph FFS. It dropped to a more respectable 21mpg by the time I got to Newcastle.Considering the performance on tap that is awesome. The M6 might be even better being the slippier car.
I'm genuinely a very big fan of the x35d / x40d but the diesel can't hold a torch to the M6 - its only better if you do a lot of miles and don't want to stomach the fuel cost of the big petrol. That's certainly a valid justification, but if you're not doing the miles and/or couldn't care less about the fuel costs then its madness to think that the diesel could somehow be 'better in the real world'. It's an efficient and effective transportation tool but it has no charisma.
