I get that. I used to be able to overhaul a VW beetle on the side of the road with regular tools. A couple of years ago my car's transmission's computer went out on the interstate. I couldn't even get a useful error code. The shop down the street didn't have a high enough end device to talk to it. While the dealer was able to figure it out; it took nearly a month to get the replacement part. I'm car semi-literate.
