I can tell you now, I will never pay $70k for a car. The depreciation was bad enough on a car I bought last year for $21k, since they redesigned again it for 2021. I like the car and I owe less than the trade in value, but the retail / wholesale values are so far apart its absurd.
When I started over 30 years ago, I was very shrewd. I would buy good used cars cheap enough that I could use them as a daily driver for a while, fix them up a little and sell them for what I paid or more. Things went downhill when I was no longer interested in value and started buying cars for show. In
1991 I paid $8,000 cash for a 7 year old Porsche. It needed a lot of work and I got it to looking really nice with a new paint job, etc. It looked brand new. I got compliments and "thumbs up" all the time. But fame is fleeting and a bad investment long term.
The car was a money pit and I took a bath when I got rid of it because it constantly needed items. The irony is the original MSRP of the Porsche in 1984 was $25,000 or about $62,000 in today's money. Makes the Model S look like a bargain.
