The cheapest new car in 2023 is the Nissan Versa for $15,730, but most of the ten cheapest cars are around $20K. [1]
The Versa gets 32mpg. The Aptera is the same basic design as their original diesel model which got 300mpg, and it's electric. It'll be way cheaper to run, it won't require as much maintenance, and you'll be able to do your own repairs.
The current US average gasoline price is $3.42/gal. [2] If you drive 32 miles per day, that's $104/month in gasoline with the Versa. Using LendingTree's calculator for a 60-month loan, $104/mo is worth a $5900 difference in purchase price, and that doesn't count maintenance savings. [3]
So yeah, by modern new-car standards I think it's about as close to a people's car as you can get. And batteries keep getting cheaper.
Looking at the original prices and adjusting for inflation it looks like the Fiat 500 and the 2CV were about $10000, and the Type 1 Beetle was around $15000. So $25k does seem rather high for a people’s car.
I’m not sure the prices I found (450k lira, 350k francs, and 4000 marks) are all correct though.
