I study the new and used car markets for over 15 years now, and I'm very confident in saying that we will hit $40,000 well before we ever hit $50,000.
The current average new car price is $45k. With the exception of Toyota, most dealers now have a lot more vehicles to sell, but interest rates have made a lot of the higher priced ones a lot less affordable.
If EVs become wildly successful, which remains uncertain, you may see a $50k average but then you would have to factor out the portion that is negated by the tax credit.
I recently wrote about the fact that small cars are becoming extinct in the USA. That is true. We're down to four and I don't really see the Versa, Rio, or Mirage surviving another generation although the MINI Cooper may hold onto its premium small car niche.
My advice? As a dealer who has covered the used car market for nearly 15 years now, is to wait until EVs become cheap. That will happen within the next five years. Then keep your ICE vehicle for long trips and bad weather. We're still at the very beginning of a long journey that will see our industry become consolidated and less profitable than ever.
