Mazda, and I am on my second CX-5 since 2016, has maybe 3% of the US market share. So of course he isn't seeing a lot of them.
Modern cars are soooooo much better than the cars made from the beginning of the car boom to the 90s and such.
Gas mileage is better. Safety is better. Technology is better. Sound systems are better. There isn't a single thing about cars these days that's not head and shoulders above their earlier versions. Not one thing.
1970 through the 1990's and a bit beyond your car was falling apart at about 80k miles and was a POS before it hit 100k and valueless.
Now at 70-80k miles they drive like they did when you first got them if you do the same regular maintenance you did on prior cars. You can get double the use and miles out of New cars.
Yeah they cost more. But so does lettuce, mulch, a haircut, underwear and everything else since the 80's.
Which was decades ago by the way.
