All my personal cars are junk. I have my gf's old 2004 GMC Canyon (yellow single cab), and my Dad's old, rusted 2006 Dodge Charger.
I'm sentimental and perpetually broke, hate payments, and prefer to save, thus a nicer vehicle is a ways away.
However, even with Cheri's Jeep Sahara 4×E she took possession of in 2021, we don't really obsess over it too much. She actually more fussy than I am. I coated it with Optimum Gloss Coat (my vehicles wear Opti-Seal through the winter. Beads terrible, buy has hung on admirably - its not really a beader freshly applied either..), which is a relatively low maintenance coating, and wash it as needed. It was more difficult in the colder temps, but the occasional touchless automatic was used a few times.
Last weekend I gave it a good bath with Power Clean and ONR and it looks like I just polished and waxed it.
I think I've mentioned elsewhere that when the next vehicle I purchase arrives I might be a little more "attentive" than I've been with these. That poor Canyon... it lived a life of luxury with Cheri. It's been garaged here since 2015, pampered washed, fluffed, buffed, etc. As soon as I get it that clear coat started flaking off the hood, roof, and pillars.. And I thought I over-polished it. Nope, that stuff was as thick as a brand new cigarette wrapper! And that Charger... One of my friends was busting my chops because he's "never seen such perfect paint on a rust bucket!
