Great question and some delightful and thoroughly technical answers. Now for a gushy one...
My first new car was a 1986 Toyota Cargo Van in white. I was graduating from a 1972 Fiat 4-door sedan in avocado green. I've never been exactly fashion-forward in style. Once I had that white cargo van I discovered that when I hung a long pillow out of each front window, a short pillow out of the liftgate, and fishing rod whiskers and a pink pillow on the front bumper, that little van made a passably cute bunny rabbit for our local Halloween parade.
My best friend went with me to shop for a small truck but when I saw the van I guess that part of me that grew up wearing Birkenstocks in Santa Cruz, CA said no to the truck and gimme gimme to the van. Never mind that my legs and the rest of me sat in the car crash crumple zone.
It was the Spartan trim level, meaning it had no bells or whistles, no rear anything over the steel drum walls, and no passenger seat. That's what I could afford. On my first oil change the dealership installed a passenger seat for free. That was a welcome surprise and one my mother appreciated. She had been sitting in the well where there should have been a passenger seat, over the engine (precursor to intentionally heated seats), and even with a Scheherazade stack of pillows the arrangement did not suit her at all.
Then a road trip to San Antonio, TX where my brother and I did the obligatory insulation, wood paneling, and carpeted the ceiling. In the mid '90s the distributor died. I couldn't afford even the remanufactured ones and '86 was an expensive repair job because everything was packed like a lunch box under the front seats. So I removed the distributor, unwound and rewound the copper coil, and reinstalled it. Fortunately the pantheon of gods who oversee starving artist engine repairs were with me and it worked.
Long after I sold it that cargo van is still showing up in my dreams for new and weirder adventures. Jump ahead almost 30 years, a few cars, and the good fortune of marrying well above my economic station... Our Subaru Outback had turned in its resignation and we needed a vehicle that could tow at least 3,000 pounds, preferably a hybrid, with enough climate control that my sweet bride and I could ride together comfortably at different temperatures. The big vans were out because their ground to floorboard height was more of a climb than we could see ourselves aging with.
When I found a 2022, low mileage, dark blue, brown leather interior, Platinum Sienna up in Seattle, WA we made the drive from Portland to bring it home. My wife has no end of fun teasing me about the visible glee I drive this with. Since my wedding vows included "love, honor, and amuse...", my Toyota Sienna helps me fill a pivotal duty in my capacity as CEO of "HappyWife Industries".
It readily tows an 8x12, single axle, enclosed cargo trailer with my woodworking materials and tools and on many days the cavernous van cargo capacity means I don't have to tow the trailer at all. At the suggestion of this chat we installed an Ecohitch and we've made a date with Kendall Toyota in Bend, OR for a 3 inch lift.
The way I figure it, my collection of Carhartt bib overalls and my Sienna van will never land me on the cover of any fashion trend magazines, but they will always be handsome enough, very comfortable, and exceptionally useful. Given my ambitious honey-do list, useful is the most important to me. Still, I'm happy to take that with a side order of visible glee.
I look forward to reading more chats about you and your minivan love stories.
