Note that the "M3" existed over several generations of the 3-series. The early M3's are actually 4 cylinder. And E40 is definitely a model code; I think it's a fairly old model, but I'm not a BMW expert.

AFAIK E36 was the old BMW 3 series.
The current one is E46.
I think....

Nark is right.
THe e30 was the older one, (pre about 96) the e36 is the recent yet not current model shape and the e46 is the current model.
The current m3 is 330, which is a 3.2 litre 6. Most definately not a 318i 2 litre 4.
So, check under the bonnet and if as stated before, it has a six in there the full six throttle bodies and really goes like stink, then it could be a m3. However, I would suggest it is highly unlikly, given the engine bay sized used to house the 4 versus the engine bay size used to house the 6.

the bays are the same size for the whole 3-series range....if it has a 6 cylinder instead of the four then you know its better. if it has the 6 throttle bodies, its probably a m3 engine.

afaik, the 3-series had 4cyls (318) and 6cyls(328, 330 etc). so seeing a six under the hood isnt a sure fire sign of an m3 engine. only the oldest m3 had a 4cyl i think... not too sure.
if it hammers hard, then id say its an m3... like someone said, hex throttles should be a big giveaway...
cheers

How old is ur mates Beemer?
The last few of series of M3 were inline sixes. They would have six throttle bodies also. I don't think the M3 ever came with a four. None of the ones I have seen or read about....

The M3 definitely came with a 4 cylinder engine, in the 80's. You guys are talking like there was only ever one M3, but in fact there have been several! The current one has a 3.2 litre inline six, but the older ones came with a 2 litre (I think) 4 banger.

....hang on a second.
I thought the BMW model codes worked like this.
First digit indicates the series of the car.... ie 318i is a 3 Series.
Second two indicate Engine size.... 1.8L
and the i stood for injected.
So 318i is a 3 series with a 1.8L injected motor.
a 330i would be a 3 series with a 3L injected motor.
Am I wrong?

Yeah, thats the theory on how it works, but they changed the engine, and didn't want to change the name "318" as it was familiar to people.

Early M3's definatly had 4's. It was a a E30, had 4 round headlights at the front. It was a 2.5 four. You would know if it was a M3 motor. Pulls 0-100 in 6.5 secs...... you should know anyway.
M5 had the six cylinder motor. Early M5's had the standard 3.5 litre motor with a body kit.. Later M5's in the same body shape had the M-Power motor..

Yes you are right, they used to be 318 = 1.8 and so forth, however recently, IE model e46 they have changed it in the 3 series so that everything is .2 of a litre above what it is listed to be, IE 316 is a 1.8 and a 318 is a 2 and the 330 is a 3.2

Almost right. It would be straight forward if it was across the board like that...but its not 
This is true for the 318i and 320i, but the 325 and 330 are both accurate, with 2.5l and 3.0l respectively.

Is it possible to get a pic of this motor and the car it's currently in? I'd be interested in seeing what management it's using too.

Don't "M" engines have a big "M-Power" emblazoned over the cam covers?

jza70-mel is right, all M power plants come with such rocker covers.
(Unless the guy just put in a 6 and whacked a M power rocker cover on, wouldn't be the first time someone did this.) No M power rocker cover? then its not an M3,
