QOTD: What’s The Most Expensive Car You’ve Ever Owned?

300SDL top 1

Today we present a bit of a mental (and mathematical) exercise for the readers. The headline is slightly misleading. We’re not looking for the most money you’ve ever paid for a car; that would be too easy. What we’re looking for is the most expensive car based on its original MSRP (adjusted to current value) that you’ve owned.

The basic premise is simple, and the methodology will be explained below.

Start with a list of cars you have owned, focusing on the more expensive models. Then find the original MSRP, run that through an inflation calculator, and figure out what it would cost you to buy brand new today.

This will work best if you live in the United States. If you live elsewhere, try your best to play along with the resources that are available to you locally.

  1. Compile your list of fancy models you have owned.
  2. Find the MSRP for those models. For vehicles sold between 1984 and 2014, there’s an exceptionally good resource at the Michigan Secretary of State Website (Starting in 1984, Michigan charged registration fees based on MSRP, which is why this resource exists.) For model years outside that range, do the best you can with an Internet search. If your car any significant options, add a ball-park number for them.
  3. Run that MSRP through the US government’s CPI Inflation Calculator. Set the original date to January of your car’s model year, and the result date to March 2026.
  4. Comment with your top answer (or your top 3, if you want) in the format [YYYY] [Make/Model]-[MSRP]=[value today]
    Example: 2000 BMW 740iL-$66,400=$129,894.21

The lede photo is the giveaway to my personal list topper. My top 3 are:
1. 1978 Mercedes 300SD-$23,700=$125,216.77
2. 1990 Cadillac Sedan Deville-$27,540=$71,381.99
3. 1985 Volvo 745 Turbo-$21,340=$66,793.80

A couple of notes to my list. I bought each of those cars as 15-20 year old beaters, and didn’t pay more than $2000 for any of them. Also of note, my current daily driver, a 2017 Mazda CX-5 Touring FWD, falls pretty low on my list as $25,915=$35,239.27.

We hope you have enjoyed today’s thought exercise and thanks for playing!
