Good call, but not necessarily. UHP tires like PSSs just wear horribly without rotation, even if everything else is in order.

Rod bearing wear rate wears out by time spent at 8000rpm. If you set the limiter to 7500rpm, you'd never need to replace them. In a track car living at the limiter, they will probably need replacement at 50,000 mile intervals.

Do them as oil analysis dictates they need to be done. Not buying a car because it hasn't had a service done that it may not need at all seems silly to me.

My Ride: e46 M3
I bought my 2006 M3 coupe 6MT with 122,000 miles. I drive around 40 miles a day for my commute mostly highway here in socal. Right when i got the car i had the valve cover gasket replaced and the vanos checked. Did a coolant flush and replaced the thermostat myself. replacing the fan clutch tomorrow. other than that the car is incredibly reliable. going to check out the subframe when i put my new KW coilovers on this weekend. ive owned the car for a little under a year and it has about 132,000 miles on it now.

My Ride: 06 M3 conv E46
Lol

It's 2 years old posting, but it's funny I have to reply.
E46 M3 is NOT a reliable car.

I have 2006 M3 vert, and for the last 8 years of driving, I replaced vanos, fixed oil leak, replaced water bump, replaced fanclutch, fixed another oil leak, changed heater valve, timing chain guide bolt backed out so replaced it, emergency brake never worked, window regulator is going out on both window, the bolt holding window glass backed out twice on both side so i used loctite last time, replaced clutch and flywheel.
I DIYed most of these and spent about 5k.
Otherwise, i probably have spent more than 10k for the repair.

Someone in the reply said he spent 10k and he said M3 is reliable.

Ya ya ya this is a high performance car.
Well... Japanese high performance car doesn't seem to break down as much.

My Ride: 2004 M3 Convertible
I've had my 2004 for over 5 years now, daily drove it for almost 3 it those and put about 45k miles on, even took some long trips. Is it reliable? Yes. It never left me stranded, and never broke down. However, I also stay extremely on top of regular maintenance and inspections. So, to give the accurate answer: is it reliable? Yes. Is it cheap to run? No. At least not if you want to daily it and maintain it like it should be maintained.

In general I would say yes, but it is not a Toyota or Honda. It requires upkeep and maintenance. It can be expensive.

My Ride: M3 vert
I daily drive my '04 vert and love it. Bought it 2 years ago with 45k miles and now have 61k so don't drive a ton but take it everywhere. I'm in the second season of autocross and can keep up with the new Camaro/Mustangs. Upgraded blistiens put me in STU and still keep up with much newer cars. I do enjoy doing the maintenance myself so not as expensive but parts on the M are much more than non-M e46 and way more than US or Japanese cars.

My Ride: 2005 E46 M3
I have 05 manual it has 118K on it (I bought when it had 93K). I have been using it as DD for 3 yrs now. It has never left me stranded. Replaced normal maintenance items (alternator, fuel pump, water pump, and Rtabs). So far the Vanos has been no trouble and my subframe is still good. I find it remarkably reliable and cheap to fix if you can do it yourself.

My E36 M3 is getting close to 250,000 miles, it's been so good it prompted me to do my current M3 Touring swap.

My Ride: 2006 M3
I drive mine daily for the last 3 years. I just make sure to upkeep the maintenance and especially oil changes. I also send oil samples to Blackstone yearly to know the status of my rod bearings.

It surely puts a smile on my face every time I drive it...exactly the reason I bought the M.

My Ride: BMW E46 318i
Used to own one, switched over to a 318i LPG. I suggest you not to daily drive a E46 M3 since it eats alot of gas, attracts police and is very unpractical (the coupe, i don't know about the sedan). It does not have alot of space, expensive mainetenance (depends on where you live), it's rough, stiff and many more. Although the E46 M3 is one of my favorite cars and one of the most fun cars i have ever owned, it is very unpractical. If you want to daily drive an E46 M3 atleast get a sedan. I'd recommend a 330csi if you're looking for both power and Practicality.

My Ride: 2005 M3
I think it is important to differentiate between High Maintenance, Reliability and perhaps Operating Costs. I have owned mine for 4.5 years and it is daily driven. I purchased at 140,000 and it currently has 190,000. I would say the car is very reliable. It has never left me on the side of the road. The closest I've been to been stranded was my battery light coming on, on my anniversary weekend while my wife and I were out of town. Fortunately we were still close enough to civilization (headed to the mountains of North Georgia) and I was able to drive to a European auto repair shop in the outskirts of North Atlanta. They got me fixed up in 3 hours, Bosch Alternator, belt and oil change for $789 while my wife and I went and had Ice Cream and walked the little downtown area. Turned out pretty good. All that to say, that could have happened with any car though.

Someone posted earlier that you pro-actively maintain these and that is a great description. Go after the maintenance before it comes after you and this will be the one of the Most Enjoyable cars you can own.

Basic Consistent Operating Costs: based on 10k/year
(YES, there is more maintenance than this. This is just basic consistent)

*Premium Insurance
*Premium Gas and not the most fuel efficient About $50 Week
*Premium Oil $80ish DIY/ $120ish Dealership I like to do mine every 7500 miles ($150/ year from dealer?)
*2 Rear Tires a Year (Depends on Brand $600/year?)
*2 Front Tires every other year ($250/year)
*Clean your Air Filter (DIY free)

My Ride: 03 M3 Vert 2005 745i
I been Dailying a m3 vert with 143k for almost a year now. I got it at 130k. Left me stranded a couple times but no big deal. I think the m3s are more reliable than the non ms if you have a manual.

In 1 year I had to replace:
Radiator, ps hose, electric fan, clutch switch, alternator twice, Lcm, shocks & springs, & fuel purge valve. I replaced a lot more then that, but that is the stuff that needed attention.

My Ride: 2002 ///M3
I've been daily driving my 02 M3 for 2 1/2 years and it's been very reliable. It left me stranded once due to a fuel pump failure, which I should have anticipated given the mileage when I got the car. Other than that it's been rock solid and hasn't even cost much in maintenance. And when I say daily driver, I mean all winter as well as summer, rain, shine, ice, snow, you name it. I have a set of blizzaks on cheap aftermarket rims that I swap over once it gets cold, and it's as good as any AWD car I've ever driven in the snow.

Recently I discovered a rust spot, sadly, so it's finally going to cost me a few bucks, but I can hardly complain at this point.

I dd'd mine from about 150k to 210k. It left me stranded 3 times: Once when the driveshaft support bearing failed, once when the fuel pump died, and once when the starter failed. So those were all mileage related failures so at high mileage I wouldn't really say its reliable.

Eh, or you can realize that some components wear out with mileage and replace them before they fail.

Pretty much the key to having any high mileage car be reliable.

Eh the closer I approach 200k, the more often I'm getting weird issues here and there that are not well documented in the community. I don't think I will daily drive this car anymore from next year. Whether that means I slowly bring it back to stock and sell it altogether I haven't decided yet.
