I think that depends on what you classify as "extremely cheap". The cheapest car in the U.S. market is the Spark at under $14k, but it's been discontinued. The Versa and Mirage both start around $16k.
I'm unaware of anything else under $20k, although the Ford Maverick is impressively reasonable at $21k.
