More horsepower does not mean you will burn more gas. This has been proven over many different vehicle types and motor power levels. Comparing the X5 M mileage to a 50i mileage specifically, there will not be much difference, if any at all. 50i and M guys can chime in with this, my 50i mileage is tracked to, so if any M guys wanna show there mileage, we can compare, to prove or disprove what I think.
I don't want to get into a deep theory breakdown, on cost of ownership maintenance wise, as I just don't know for 100% certainty what either would cost to maintain. I do know cars, and trucks, very well. I can say for 100% certainty, that if I owned an M instead of a 50i, the only thing that would cost more, would be my monthly payment. No ifs ands or buts about it. I don't believe there is a costly valve job that the 4.4 V8s require, I will have to read through the workbook on my motor (N63) and see for my application. I would never pay someone to inspect my own vehicle, I would, successfully complete the valve adjustment on my own, and the price of brakes would solely be determined by how cheap of a person I am when it comes to buying them. I would also complete the installation. For me yes, it would be, identical. I say this as a twice Master OEM, and current ASE master technician.
For everyone else, yes, again I say, the operational costs would be negligible. With a bit of wit in parts purchasing such as, the one M owner who found out the M brand plugs just cost more because they spec'd specifically for the M, come to find out, there is a regular BMW plug that meets the same standard as the M plugs, and works just as well, I truly believe the cost of ownership is NEGLIGIBLE (as in different, but not in any noteworthy sense, something like a few hundred dollars a year, at absolute max)
I hope I don't come off disrespectful in my post, I was delighted you were pleasant in your disagreement of my other post, but I want to clarify better to you what I meant, as I did not explain in depth about my previous post. I believe this may bring a moment where you may agree with me. If not, no big deal, and cheers anyway.
