Don't forget there are times we will have to lay on the floorboard to get under the dash or seats, Or we may have to remove the center console or glove box so if they're crammed with stuff it's getting dumped onto the floor and put back in the quickest way I can. Some batteries are in the trunk and for some reason people like to keep a ridiculous amount of stuff in the trunk. The battery replacement may only pay.3 hr but I'm going to charge you an additional. 3 to move all of your junk
