Hi,
Driving a M5 three miles to work and then home again is like driving a F16 up and down an aircraft-carrier deck without actually taking off !!
Fun for the new owner, but doesn`t really allow you to use the perfomance
Seriously though,
I don`t know of any short to medium term problems with using it for such a relatively short journey, although you are of course right about the warm up time. Keep the revs low, I would suggest about 1000-2500, definately under 3000+ until the oil temp guage climbs away from its stop.
If other board members say there will be trouble, then have you considered buying a cheap`n`chearful car for the daily drive? I`ve seen autotrader.co.uk knocking out E30 320 & 325 for £800-2000.. Try these I just got from the web.

Why not get something like this, a FSH for under £2k ??
You`ll only need third party fire & theft insurance. .
Now this may now have the presence you want turning up at the office, but you wait til you see the bosses face when you turn up at the country club on the weekends in the M5
Dealer Servicing.
Recommended if you can stand the bills. I`ve fallen out with my local main dealer and take it to a specialist for most work.
You`ll need to take a look at one of the books, for example the Bentley (useful) or Haynes (spit!), they`ll give you the list of whats needed in and inspection I and II service, albeit for the 5 in general.
If you`ve serviced before on other cars, then maybe its worth spending the time on this one. Its amazing how other hobbies pale into insignificance when you own an M5.
I do everthing (or get help), but I won`t tackle the valve clearances & shims.
Mine is an older car, so the £800-900 for a main dealer inspection II is just too much to bear, but if you have the cash to consider the later 3.8 cars, then its quite nice to keep up the FSH, but make sure the specialist you take it to knows what they are doing. Go and see them, look around, you soon sort the wheat from the chaff. Don`t be afraid to use them , but take it to a main dealer for the more "involved" jobs, eg shims, self-levelling suspension adjustment/replacement, if the specialist doesn`t do them regularly. Remember, BMW only officially sold under 700 cars to the UK, so not everyone works on the M5 specific tasks that aren`t on a 520/535 etc.
I`ll leave the other repliers to your question to fill in the exact dealer prices for each routine job.
Ivan.
PS. These M5s are like girlfriends. If you want a really really nice one in top condition, then use it regularly to the full as its going to cost a fortune to run it !!!
