i am considering a 2004 or 2005 M3 convertible, manual (not SMG)and i would like to ask what maintenace/problem issues i should particularly be aware of when shopping for one. also, i would like to know the owner's opinion of the reliability of this model.

lastly, i'm having a hard time finding all the dealer options offered for the two years. if you have links or can list, that would be helpful as well.

any advice would be appreciated. thanks.

p.s., i currently own an e34 540i. so i an somewhat familiar with the older bimmers.
