    Cost of operation E28 535i vs. M5?


    Is the upkeep on a properly maintained M5 going to be that much more than a 535i? Had a high mileage 535i, so am familiar with its costs. My sense is that a M5 will be less reliable and have higher parts costs.

    And what should I worry about in buying an old M5 with average mileage? Most I've seen have been well taken care of.

    Thanks for reading my post...Theo.

    I've always said" either have deep pockets or be able to perform work yourself" when owning an M car. The M5 is no less reliable unless you factor in the mandatory timing chain/guide work every 100,000 (or less),IMO.

    I agree entirely

    I do most of my work.. yet occasionally I have others do simple stuff.... they ALWAYS charge more the second they see the M badge. It drives me crazy, this is for even the simplest of work, that is no different than a non M car. The more that happens the more work I do myself.

    The M5 is no different than any other well built high performance machine.. Do the maintenance and it will work well for a very long time. let it slide and the money to revive it will be prohibative. If you are buying a used car.. It is all about proof of maintenance, and test of actual performance. Cleanliness is also a key indicator of a fanatic owner. There is no subsitute. I always clean my engine bay before every service visit. that way the mechanics know they have to do a spotless job. If the engine bay is dirty I have no confidence that any repair work was done meticulously.

    Hi Steve.
    Sometimes I wonder how long I have left before mine will "need to go to a good home", i.e. someone who can do the work themselves. I'm married now, and I don't have a lot of disposable income, if you know what I mean.
    Do you remember my black/black ///M5?
    It has 120K on the clock. I've put 20K on it during the 2.5 years I've owned it. During that time, I have had the following done (not in order):

    Timing chain
    Scary plastic chain guide
    a/c condenser coil
    upper/lower control arms w/ new 750i bushings
    (all above courtesy of you)
    All new cooling system: radiator, water pump, hoses, etc...
    Replaced air intake bellows (or boots or whatever you call them) between the intake plenum and the throttles
    New battery
    New flywheel sensor

    I think that covers most of the major repairs/refurbishments.
    The only thing pending is replacing the driveshaft. I wonder if there's anything left to replace;^)

    That's exactly what Carl Nelson told me 10 yrs ago

    He was right! Actually if you are very proactive with the maintenance, you can make these cars/components last much longer!

    Other than the major $s spent on the timing chain replacement, I really haven't spent much more than I would have on a non-M car. (knock on wood...lol)

    If you suffer from OC disorder, any car ownership will be expensive!
    Cheers!

    Re: Start thinking suspension

    The previous owner already thought of that.
    Dave Harrison (of Harrison Motorsports) replaced the entire suspension with Bilstiens and Eibachs.
    And, some other go-fast bits:

    Autothority Chip
    Bigger exhaust cam
    Custom fabricated Levinson exhaust
    Euro exhaust header
    Previously mentioned suspension replacement

    And some other things I can't recall at the moment.
