LOL! Oatmeal cookies w/raisins, please!
I understand where you are coming from. Here’s the deal. All of my cars are the older vintage,I have toolboxes in each one.
Now if a newer rig breaks down (it DOES happen), then you:
Call your onstar thing to get a tow..
Wait at the auto shop for them to plug it into the Cray supercomputer
Wait for the ethernet WAN to get established to some outfit in Malaysia
Have them run the diagnostics
Sadly discover that the link to the ordering joint is down so they can’t order your part from Bulgaria for the next two days
Get to come back in two days, pay $320.00 for the part, and another couple C’s to get it put in.
Now I go to the auto parts store, put $39.00 on the counter for a new alternator (plus tax, can’t cheat the governor), drive home and 45 minutes later, it’s in.
Now I don’t HAVE to fix my stuff if I don’t want to. Somebody else could do it, but I chose to do it.
With the new stuff... you HAVE to let an authorized dealer/technician do it. Or you will either void the warranty or mess it up so bad you might as well junk it.
My apologies. I tend to put things into a single-guy-who-takes-everything-apart-and-puts-them-together-better perspective.
