This can all be true, but overcoming 40 years of neglect and almost-rans is going to take time these companies don't have.
When I went shopping for a new car, I wanted to lease a convertible. My main choices were the Miata, the Solstice, and it's Saturn cousin the Sky.
Saturn didn't lease, so it was out. The Pontiac looked pretty cool, and technically had a faster motor than the Miata - but the interior felt more confined and less refined. The top went into the trunk which took up like 90 percent of that space. In order to put the top down you had to stop the car, get out, unhinge the back section and lift it up, fold the top into the trunk, and move some covers on the roof snaps or something like that. The Miata - I just pull a latch and throw the top backwards and it locks into its own storage while I'm at a light. Getting it back up in a hurry is a nice feature for unexpected rain storms.
It's another example of marketing over function. It was a lot more about how cheaply could they make a car that looked cool at the dealership, and less about what people actually want in a car.
For my next car I am seriously considering a Ford - I love the look of the new Challenger too, but will there be parts for it a few years from now?
