I don't know what the hell kind of bmw you were working on, but 1) I've taken the battery in and out on mine probably 20 times. Yes, it is in the trunk, but it takes all of 5 minutes to pull the flap back, disconnect the terminals and pull the battery out... just like any other car, and 2) there wouldn't be room under the hood for the battery in mine, unless stuff was moved around. But advantages of having the battery in the trunk (since you said BMW did things differently for no reason) include easier access that doesn't intimidate more non-mechanical people (ie women :huh:), more options when using your car to jump start others (there's a spot in the front under the hood that's a positive battery jumping location, as well as the battery itself in the back). I could probably come up with more if I bothered to think about it.
Anyway, I'm not a mechanic, and I've done a number of things on my car, and I can honestly say, it hasn't been any more difficult to work on than any european or japanese car (I think I said this already). Yes you may have to do an ounce of research to find the part that's supposed to be in one spot, but bmw decided it made sense to put it somewhere else, but all in all, they're not hard at all to work on. Stuff I've done includes: changing starter (admittedly kind of a *****, cause it was hard to get to, but no harder than on my old '98 corolla), changing spark plugs (very easy, only difference between any other car was needing to pull off two panels that cover the plugs and wires. they had 2 bolts a piece to take them off), draining and refilling the transmission (had to buy a couple of the rarer tools, but overall not terribly difficult either), and troubleshooting and repairing a failed connection between the battery and the starter (this was probably the only one that I thought to myself "seriously BMW, that was stupid of you" because it turns out they put a pyrotechnic charge that severed the connection between the battery and starter when I inadvertently set it off. (don't ask how). They call it a safety feature, but I don't see how it's anything more than a pain in the ass.
But overall, not any more difficult than any other foreign vehicle, although it is true that parts tend to be a bit more expensive. But hey, I can afford it.
If you choose not to decide, you still have made a choice.
