Yeah, I'd like to punch the guy who decided to put batteries down low thru a fender well knockout. There are accessible +/- terminals on top, but you cannot access the battery itself at all without a bunch of disassembly and laying on the ground taking 17 screws out of the fender knockout panel. Being able to quickly access a vehicle battery is one of single most usual maintenance items on a car.
Of course, the first time I needed a new battery (Napa's best for the application), it wasn't until it was all installed that I discovered it was a bad battery. What a PITA. Oh, but the practice was invaluable.

Pulling the entire Dakota dash panel/steering wheel for a few dollar heater coil is also worthy of a public flogging. I told her to just wear warmer clothes..... but you know how that worked out.
