I don't know where to start looking.
Is there a webpage that has all known issues for 2003.5+ M3s?
I'm currently looking to get one but would like to know what I'm in for.

Thanks for the help!

 

There are no substantial recalls on 2003s. You can reference this page.

I would focus on the documented maintenance record, ensure scheduled maintenance was done, oil was changed AT LEAST on schedule (more often is better, but rare) and that it has a clean CARFAX.

Is it a 6spd or SMG?

Good luck, owned one for 4 years and because of all the issues I now drive a different brand. My car had less than 32k miles when I sold it. If you do it, make sure its CPO'd and still under warranty.

thanks for the info!

I'm looking for SMG right now..

 

He asked about a MY2003.5

The majority of the SBs you cite appear to not be relevant to a 2003 E46 M3.

 

Josh,

Thanks for the links!

 

Hmm any opinions in regards to SMG? I read through the FAQ and it might not be what I'm looking for. I MIGHT want to get a 6spd instead.. Only if I could just get out of this traffic hell...

 

I have a 2003.5 6MT and love it. SMGII would be nice, but I would find myself getting bored. Nothing like a revmatched down shift

 

i had an 03 and never had a problem with it, very reliable, i think more of the issues were with smg's, i sold it to a member here riverflyer and you can ask him how it is going. great all round car can't go wrong in my op. just make sure the rod bering recall was done

 

i had an 03 M3 - lets see the subframe was tearing apart from the rest of the car and had to be replaced and i was out of warrenty at the time and it was done for free for me and at this same time my trans (SMG) decided to stop downshifting from 4th to 3rd so the trans was replaced too...under warrenty even though i was 6k miles over... other then that, your window/door liner WILL go and its about 500 to replace on either side - other wise... great great car

 

or a dollar's worth of Gorilla Glue...

 

tried eveything there was cept that glue... still kind of a ghetto fix, took it to bmw had it done right

 

i had the trim on both sides come down in the past two months...took it to my bimmer dealer and got it fixed up and its perfect now.

 

can you find and post all the SIBs for the clutch, i am having a strange sticky clutch pedal issue and think there was a SIB

to the OP, dont forget to check m3forum for more info on 03.5 E46ers
