Brand loyal or just like a good vehicle?
I have yet to own anything besides a Mopar or jeep.
Sorry, Hondas Toyota Hyundai Kia BMW Nissan aren't even welcome in my driveway. Never were never will be.
I have scaled back on side work, and even when I was doing more of it, I would tell people who wanted work done on any of those, "sorry, I have no service information on them and don't know where I could find it".
