Geez, I just read through several pages of comments from people too fat or out of shape to get in and out of a pony car... as if it's the car's fault you're out of shape.
If there ever comes a day when I can't execute the basic life skill of climbing in and out of a car with relative ease, I certainly won't be telling the internet about it.
Average men over 60 in the US are 5'8". Average weight is about 195.
I'm 6' tall, 225. I am not overweight, and all of my bloodwork numbers are fine. I'm just large framed. I usually consume over 4000 calories a day and don't gain weight. There's no fat on my shoulders, as I can feel bone directly under my skin, yet my shoulders hit the windows in many cars.
My feet are size 13, have been since I was 12 years old. On many cars, I have trouble getting my foot on the gas pedal without hitting the brake pedal, because there's not enough room between the brake pedal and consoles.
Some cars I put the seat all the way back, and still I have no room to extend my legs, which makes for very uncomfortable driving.
My mother in-law had a Toyota Seneca van, and I was very uncomfortable driving that. Seat did not go back far enough, and did not lower down enough, making it hard to see out of the front windshield very far down the road without hunching over.
There's all kinds of body shapes and sizes. Cars, especially economy cars, are built for average sized people.
On the other hand, our 2020 Subaru Outback, I have to move the seat forward 4" to reach the pedals. I have to move the seat forward on our 2003 Suburban and 2013 Impala as well.
So it'll be 4 door sedans, wagons, Suburbans for the rest of my life.
