I got my '08 last year with six months of remaining warranty; I'm sure I paid a little premium because of that. It definitely paid off in my case, however, as I got several things taken care of before my factory warranty ran out (one would have cost me $3000). If I was in the market for an '08 now, I think I'd be looking for one that's CPO, just for the peace of mind.
That said, finding one with such low mileage is very tempting... but if I was going to spend $45-50k on an M3 right now, I'd find an '09+ with remaining warranty.
If you're already stretching you finances some to get into car like this, a big repair bill could mess up your situation.

Clarkson: "It is... pretty much perfect... Why don't I have one of these cars?"
Harris: "The saloon is definitely
the M3 of choice."
