Hi Sajeev,

I enjoy your columns for their history and technology surprises of what might be wrong. Two history questions:

Since I have always been a penny pinching cheapskate and introvert I have never had an interest in large cars or silly awkward pick ups that burn lots of fuel and make lots of noise. Anyway, I don’t know what an auto Panther is or why several people at TTAC seem to remember it with fondness. Apparently the word has something to do with a frame built by Ford for many years but what is special about it and what is its history? Perhaps this could be worked in to one of your columns while helping someone with such a vehicle.

Many years ago I switched from Volkswagens to Toyotas and my life is now boring with no repair drama (or insults to my dignity from VW dealer staffs) and I haven’t been involved with auto repairs. A friend with a 2006 Prius with 90,000 miles asked me how long her car’s nickle metal hydride batteries would last out here in Phoenix’s hot sun. Any thoughts and history about this? Can the batteries be replaced with Lithium Iron Phosphate batteries?

Thank you,

Lynn E.

Sajeev answers:

Quite frankly, your life is boring to the point of shame. And not because you can’t comprehend Panther Love, explained and defended here and a decent year-by-year analysis given here by yours truly. But because your life never included proper American Icon.

VWs and Toyotas are fine, but there’s more to automotive life. Especially in the American South, where we pride ourselves on our proper American rides, even if they are swanga’d customizations of some of the worst machines in General Motor’s history. But the Panther is an amalgamation of the best of Americana, it’s the right sauce for many people’s palette.

Put seriously, these cars have merit even if they will never be mainstream. So if you don’t get it, don’t sweat it. It’s all good.

About the friend’s Prius: because Hybrids have a temperature control system for their battery packs, Arizona’s heat isn’t as big of a deal compared to a normal battery under the hood of a steaming hot engine. I expect for Arizona heat to tax the system more than other regions, but this article does a good job putting it into context. Maybe one of the fixes and preventative maintenance suggestions in that article will significantly extend battery life. Or–as we used to say around here–not.

So let’s wrap it up: Toyota warranties these systems for 8 years or 100,000 miles. Much like Hyundai’s insane warranties, I have little reason to doubt that Toyota did their homework. Car companies don’t usually gamble with their cash flow in such a dangerous place. With any luck, your friend has a few years of life left…fingers crossed on that.

Send your queries to sajeev@thetruthaboutcars.com. Spare no details and ask for a speedy resolution if you’re in a hurry.

My fiance seems like the perfect candidate for a Prius. She's fairly frugal, keeps cars until the wheels fall off (seriously... she's 34, and on her second car... which is a 6 year old Versa), likes to try to be as green as possible, and doesn't care for the act of driving all that much. Can't say I get the Panther love (though admittedly, the only Panther I've driven was my grandmother's '03 Grand Marquis, before she finally gave up the pretense that she'd ever drive again... Whenever I'd visit, I'd take her out for lunch and errands driving her maroon colored barge. Fiance's mom has a Lesabre, which seemed equally bad. But, color me surprised, I rented a '12 Impala last month on a vacation in San Francisco, to drive down the coast and meet some old friends. I really liked it. That car felt so solid, the power so responsive... It didn't slosh around like a LeSlug or a Grandma-Rquis. It was 100% opposite of what I expected. I still wouldn't trade my tC for one (I like having two doors, a hatchback, and a manual transmission), but I was very, VERY pleasantly surprised. Other recent rentals included a Ford Focus and a Ford Fusion - the Impala was definitely on the "Focus" end of the spectrum from the wallowy Fusion!

First learned to drive in my father's old '84 Mercury Grand Marquis. My friend's first car was an '87 version that was virtually identical. I kinda helped teach him how to drive it properly. He later upgraded to a 1994 model and then traded that in on a 2002 LTD, which I helped him out with from time to time. Over the course of the last couple decades many of my uncles have owned several iterations of either the Grand Marquis or the Lincoln Town Car and during my late adolescence, I found myself behind the wheel of just about all of them at some point or another. So yeah, you can put me squarely in the category of people who "get" what Panther Love is all about. That is all.

Honda1 Unions were needed back in the early days, not needed know. There are plenty of rules and regulations and government agencies that keep companies in line. It's just a money grad and nothing more. Fain is a punk!
1995 SC If the necessary number of employees vote to unionize then yes, they should be unionized. That's how it works.
Sobhuza Trooper That Dave Thomas fella sounds like the kind of twit who is oh-so-quick to tell us how easy and fun the bus is for any and all of your personal transportation needs. The time to get to and from the bus stop is never a concern. The time waiting for the bus is never a concern. The time waiting for a connection (if there is one) is never a concern. The weather is never a concern. Whatever you might be carrying or intend to purchase is never a concern. Nope, Boo Cars! Yeah Buses! Buses rule!Needless to say, these twits don't actual take the damn bus.
MaintenanceCosts Nobody here seems to acknowledge that there are multiple use cases for cars.Some people spend all their time driving all over the country and need every mile and minute of time savings. ICE cars are better for them right now.Some people only drive locally and fly when they travel. For them, there's probably a range number that works, and they don't really need more. For the uses for which we use our EV, that would be around 150 miles. The other thing about a low range requirement is it can make 120V charging viable. If you don't drive more than an average of about 40 miles/day, you can probably get enough electrons through a wall outlet. We spent over two years charging our Bolt only through 120V, while our house was getting rebuilt, and never had an issue.Those are extremes. There are all sorts of use cases in between, which probably represent the majority of drivers. For some users, what's needed is more range. But I think for most users, what's needed is better charging. Retrofit apartment garages like Tim's with 240V outlets at every spot. Install more L3 chargers in supermarket parking lots and alongside gas stations. Make chargers that work like Tesla Superchargers as ubiquitous as gas stations, and EV charging will not be an issue for most users.
MaintenanceCosts I don't have an opinion on whether any one plant unionizing is the right answer, but the employees sure need to have the right to organize. Unions or the credible threat of unionization are the only thing, history has proven, that can keep employers honest. Without it, we've seen over and over, the employers have complete power over the workers and feel free to exploit the workers however they see fit. (And don't tell me "oh, the workers can just leave" - in an oligopolistic industry, working conditions quickly converge, and there's not another employer right around the corner.)
