I think it’s pretty normal for people to want to take good care of things they’ve spent hard earned money on. Is driving a filthy car some kind of weird flex?
I only needed to rinse my car off once a year, max, and did that with a garden hose. It was fine otherwise. Car washes are a waste.
I have everything at home to clean our vehicles, but I can’t just run the hose during the winter when it’s most important because of the MgCl; so I’ll take our rigs to the wash if we are in town (nearest car wash is 60 minutes away) to clean the undercarriage and minimize rusting.
If my shoes were that dirty, then heck yeah I would clean them. What a mess, it's easy to get your clothes dirty when the outside of your car is filthy. My kid's white dobok is especially sensitive to dirt on the car.
Fashion statement is actually a pretty good explanation, thank you.
Whether I wash my car or not, it changes nothing - the car will get dusty and rained on over and over regardless of what I do. When I first got my car I would wash it sometimes, but it's inevitably going to rain in the next day or so and return to exactly the same state. Washing it once a year is enough to remove any grease/carbon from the roads.
Why bother? I don't think it's actually "maintenance" if it doesn't maintain the car in any meaningful way.
As usual, it varies. Some outdoor environments can cause pollen/pinetar/birdpoop to accumulate and form a layer of weather-resistant plaque which slowly degrades the paint. Some indoor storage environments are open-air, which can lead to a stubborn buildup of oil/pollution/dust with a similarly negative impact.
Of course, there's also the general idea that, if you baby something, it'll last longer. Inspecting how the car looks on a semi-regular basis might lead one to noticing any number of issues -- a soft tire, a fluid leak, a faulty tail-light, etc. It's not a bad ritual to have if you rely on the good working function of such things.
With all of this being said, I don't exactly practice what I preach... Driving bores me and I'd rather pay someone else to do the associated maintenance even though I've been thoroughly taught how to do it myself. I very much belong to the "carwashes for thee and not for me" school of thought
