A body shop is a body shop is a body shop. Right? Wrong! As with any human skill, levels of expertise and experience will vary from shop to shop and from individual to individual. Some mechanics are just better at it than others; and the collective skill of all the mechanics working at a single facility can vary—often significantly—from one to the other.
Similarly, a car is a car is a car. Right?! Wrong again! A long time ago, in an automotive galaxy far, far away, when the car industry was relatively young, one vehicle was more or less indistinguishable from another. Sure, some makes and models were simply better than others right off the assembly line. Some were known for their superior performance on the road, while others could boast about their extra-eyecatching stylish or sporty looks no matter where they were.
But aesthetics and engineering aside, underneath it all most automobiles could be characterized as “generic”: that is, they were all basically a collection of seats inside a box bolted to a chassis mounted on a set of four wheels—a self-motile machine equipped with lights and mirrors, propelled by a petroleum-fueled internal combustion engine, and controlled by a steering wheel, gear shift, gas-pedal, and brake. If it broke down, was involved in a collision, or otherwise damaged in some way far away from the dealer from which it was first purchased, no problem! Pretty much any competent mechanic could fix it. And if it needed new parts, again no problem: a good many of those parts were more or less standard and interchangeable from one make/model to another, and could easily be obtained from any well-stocked auto parts supplier.
Well, those days are long past.
