Preventative Maintenance
Hey so I am seriously considering picking up an e46 m3, and I am just scared of the maintenance costs. Is it dangerous to get one with over 60k miles on it? I will check to see if the 3 inspections were done and to see that the oil was changed and whatnot via carfax.

Also, What is some good preventative maintenance I can perform after I get it? Fuel pump/Fuel filter/ check the valves/replace bushings. how much would that cost me?

also, how much per year will it cost for maintenance and repairs. Ill do about 5k miles a year.

Maintenance isn't that bad if you can work on the car your self. I've had the car for about 2 years and have put in a little over 2k in just parts. But that's including about all the preventive maintenance you can do as well.

If your picking up a car don't just settle for a clean carfax. Take it to a shop and have a PPI done, definitely worth it!

well what did you do as for preventative maintenance? What else can be done besides what you have already done?

I still need to put in the upgraded cam bolts in and have the sub frame reinforcement welded in.

I've pretty much done all the small stuff. Rtab, fcab, rsm, guibo, tranny mounts etc. The biggest I've done was a full cooling system overhaul.

what is fcab and rsm? Besides that stuff is there anything else? Is this thread conclusive enough under part 2?

Front control arm bushings and rear shock mounts. Yes! That's the exact thread I've been following :thumbup:

And don't forget the RTABs. Rear Trailing Arm Bushings. May need replacement and either go with something like the PowerFlex or add the RTAB stabilizers.

And Shocks. Grond Control found the stock shocks lost about 50% of their dampning in 20K miles.

And of course, there are the unforseen issues. 03-28-2012 10:31 AM

I have found the M series to be a better mechanical artifact under the hood than non-M series. Having parted out both type cars since 1983(9,500 bmws)i have run across a HUGE amount of interesting little situations. Keep a fresh battery in the car(every year), don't "jump" the car off, don't over heat, pre-heat if below 28 degrees, change oil when your supposed to and you'll be good. Having said that....the average M has much less miles as a group than non-M cars. Do a pre-purchase at the dealership, their not perfect but can steer you away from a lemon....they know what to look for. The one drawback is.....everything to do with an M series car is either hard(er) to find and or exspensive...within reason. Great car for the car-nut no doubt.

I bought an E46 M3 with 40K miles. It is very reliable. Just find a good BMW mechanic in your area (ask BMW club members for recommendations) and maintenance, as well as repairs, will not cost more than a std BMW. If you 'kick' it too much, expect parts to wear. If you take care of it and don't abuse it, it will treat you well. I also have a 1989 E30 M3, which is just as reliable because I have always performed preventative maintenance and use top grade fluids and parts. Don't cut corners or you will 'pay' for it later. Again, U need to find a good BMW mechanic who knows BMW cars well. Make sure that he/she keeps a clean shop and make sure the owner is sincere. Stay away from the BMW Dealers, unless they are recommended by seasoned BMW club members. In my experience Dealers are only good for warranty work. Dealers charge a fortune and many times botch up off-warranty repairs because the job was given to an incompetent apprentice. Good luck trying to convince a dealer to compensate you for a botched job. they will just try to charge you more to fix it.
