1. Does this engine burn oil?
I drove it for the first time, it will take time to getting use to how stiff the suspension is and how jerky the ride can be.
2. I was wondering if m5 with all the adjustments it has for comfort modes, can this drive similarily to the way my 550i xdrive drove?
3. I probably kept a budget of $3000 for repairs/Maintenace a year for my 550i, and never once went over $1500 for the year. Is this a reasonable budget for the m5 yearly?
I already see off the bat the dealer that has it, the rotors are not drilled so I am assuming this is not correct and this would be a negotiating point for me for the price? is m5 brakes/rotors cost expensive - anyone know what the cost for the m5 is?
5. Now Brakes, rotors, spark plugs, filters, fuses, and some other miscellaneous stuff I can do on my 550i. Is it reasonable to assume I should have no problem in doing these items on the m5?
Thanks in advance - the one im looking at is Donnington Grey  |
-I dont believe there is much youll find about the f90 burning oil. My f10 had a tiny bit of an oil consumption problem but not to the point I would call it an issue. I mean like 1/2 quart btwn oil changes. If that. My f90, haven't had that happen at all.
-it will be stiffer than the 550i, even in comfort mode. It's been a while, but for comparison sake, I would say the m5 comfort mode is probably as stiff as a stiff setting in an 550i (if they have the setting? I cant remember it's been too long). A 2018 wont be a comp, so I believe the comp is even a little stiffer? I don't think i've driven a non comp f90, so cant remember. Personally (and I don't think i'm alone I this) like the stiffness of the suspension and chassis. I understand why some don't. It can be a little stiff if you live in a very urban area, with rough roads, but personally on a sports car I like to feel the road, and feel what the car is doing. It doesn't bother me, but would probably annoy my wife long term.
-Unless you really pound on the car (which it can handle somewhat), do a lot of modifications, or buy one that has not been maintained very well, I would say the maintenance shouldn't be too much worse than the 550i. In many ways the M5 is overbuilt to withstand some pounding with in reason. Brakes and tires will be more expensive, and not last as long, but the rest of the car shouldn't be too much different.
-The rotors are not cross drilled?? Thats very odd. Are they slotted? Aftermarket rotors? Ive never seen an M5 with non cross drilled rotors unless they were an aftermarket slotted type, which would raise another question in my eyes if the previous owner did a lot of track days, and preferred aftermarket rotors as a performance upgrade ? or Cheaper option? Yes rotors and pads will be more expensive. And they wont last as long. Rotors are reasonable though compared to some other cars. And there is aftermarket replacements that work well. Also check to see if the car was originally specced with carbon ceramic brakes. Easiest way to tell would be gold colored calipers, but thats not a guarantee as they could be painted. But majority of carbon ceramic specced cars will have gold calipers, in 2018 the others would be a blue caliper majority of the time. So check that out as CCBs were about a 8-10,000.00 up charge and could be VIN specific, so it could be priced as a car with CCB, but not have them. And if thats the case I would maybe stay away from that car in that case, as it would indicate either pervious owner, or dealer cutting corners on maintenance, or the car has been molested to a certain degree. Just would raise some concerns. I would spend some time figuring this out before signing. I just had my steel brakes (all 4 corners) done with new OEM pads and rotors at the dealer (covered free under my maintenance plan) but dealer said "you just got 6,000.00 worth of free brakes".... LOL ( I just love when a dealer says stupid, arrogant stuff like this, like I should be thankful and give him a top because they did me a favor by upholding the contractual agreement we had to replace brakes under my maintenance plan, that was paid for for that very thing. LOL, I digress... ) , What I wanted to tell him was "I would never in a million years pay a dealer or anyone else $6,000.00 for a steel brake job I could do myself in about 2 hours and 1/4 of the price, only reason i'm here is because its free bud!!! but thanks for doing me a "favor" "... I would imagine you could find online, OEM rotors and pads for a lot less than that. Probably 3-500.00 per rotor max, and pads probably 2-400.00? Not sure. Could also go with aftermarket pads and rotors as well since many of us loathe the dust, and squealing from the steel OEM brakes.
-I would imagine if you did them on your 550i, you could do them on the m5 also. Shouldn't be too much different as far as brakes and filters etc. Spark plugs could be a little more difficult. I dont know though, the dealer did mine free as well. But honestly I dont know how hard or easy it is. The motors have a lot of similarities, and share a lot the specs. Im just un-sure if there is more "stuff" in the way on the M5 that would need to be moved to get to the plugs. I know there is some DIYs here on plugs somewhere. (I think)
All in all, moving from 550i to m5, shouldn't be too big of a change in terms of maintenance and reliability. Handling, speed, and driving experiences will be massively different.
Cheers.
