I've heard that some cars have the battery under the back seat or in the trunk - not where I'd think to look.The old Volkswagen Beetle had the battery under the back seat. It was a snap to change, really easier than you might think. Push the driver's seat forward, fold it down, and lift the back seat. There's the battery, easy-peasy.
I recently helped a friend with some kind of Chrysler POS that had the battery under the engine in the wheel well. Obviously designed by an engineer who had never turned a wrench, or planned to quit Chrysler and was giving a big F-U to all the guys would would have to turn wrenches on the vehicle.
I don't know what the engineers are thinking sometimes.
Back in the day, some vehicles used to be a positive ground circuit. That's right, the positive side of the battery grounded to the frame, and everything ran off the negative cable. Those things would make you throw your hat in the creek.

BMWs have the battery in the trunk.
The Brits traditionally use "positive earth" (earth=ground) on DC connections; technically, that's the correct way to do it since electrons flow from negative to positive, not that it makes any difference in performance. Does require paying attention to connections when working on cars from Merry Olde, though.
RE: battery locations - the Jag 120s (and, I suspect, a bunch of other cars) used to have a pair of 6V batts, one in the rear of each front wheel well, behind panels attached by screws. Couple seasons of driving in salt-treated roads made getting the screws out just so much fun....
A 1964 Ford Fairlane had its battery in the trunk.
Although that was in the Thunderbolt Fairlane.

For those youngsters that never heard of the Thunderbolt, here is a good article.

I have never seen one on the road or a track, did see one in a museum though.
