Try to be, but the few die-hard and deluded Toyota cheerleaders we've had on here over the years has me avoiding the brand just out of spite. Petty? Absolutely.
I grew up with a grandfather that was a Ford die-hard (think I've mentioned that in the past), he used a GM engine to moore our floating swim dock. My dad was not brand loyal, and had owned an MG, Morgan, Mustang, VW bug, Fairlane, Pinto, Caprice...etc. His parents just bought what they liked, so his approach was pretty similar.
My first car was an Olds, my parents had an Olds wagon at the time, it was a pile, that was my 2nd car. Dad, implored by mom's dad, bought a Lincoln, which we owned for what has to be 20 years, as I ended up with it and then I gifted it to friends of ours that needed a vehicle but weren't in a great situation financially. He (my dad) has been a "Ford guy" since, currently owns a Lincoln, they've owned two Expedition's (which they still own, it's 23 years old...).
I've owned Mazda, Ford/Lincoln, BMW, Olds, Subaru (used Forester XT, dealer bought it back), and of course a lot of Daimler-Chrysler/FCA products, since my buddy owns the dealership. I would have considered myself a Ford guy for the most part, as that tended to be my default, but as I noted, I've tried to be more open minded to other options, and have shopped other options, in the last decade or so.
There are a few brands I've not had the opportunity to drive, but these are not vehicles in my price range, like Lamborghini, Ferrari, Aston Martin...etc.
Currently really like what BMW is doing, and I loved the i4 M50 (but my wife didn't, she preferred the iX M50). My M5 was my favourite driving car of everything I've owned, and my wife is obsessed with the X5. But, we love both our vehicles, so I don't see any change coming in the near future.
We tend to try and have one "fun" vehicle and one "practical" vehicle, which is why I had the M5, Charger and my SRT Grand Cherokee's, while we also had the Expedition, Durango and then two 1500's.
