Here's a question, why is the ability to go around corners THE measuring stick for a "good car"?
I reject the premise. Everyone has a different idea of what makes a "good car". Here are some ideas:
* Reliability - starts every time
* Excellent mileage
* Blistering straight-line performance
* Svelte bodywork
* Durability
* Carrying capacity
* Versatility
For the motorheads among us, raw performance counts. But there is no objective "ultimate" performance criterion.
I love autocross racing and a Sunbeam Tiger with a hot HiPo 289 and tall gears and heavily tweaked suspension will beat almost anything. But we're talking parking-lot sized tracks where you can drive the whole thing in 2nd gear with a rev limiter.
Switch gears to the Isle of Man, and it's a whole different game. There you want lots of speed, but your low-slung Ferrari is going to trash its underside.
Sebring? LeMans? Sure, trot out the Ferraris. You can still get beat there by a Ford.
Laguna Seca? Better have a nimble chassis with spot-on weight distribution.
Pick your poison... there is no "best" car.
Other than the venerable Land-Rover, that is. http://www.ameinfo.com/27240.html
