Well I like all the tech stuff, its all fancy. But give me a car where its 100% down to the driver, and it does handle, does have a bit of poke, and does stop. It has to be enjoyable.
That said, I think the MAIN thing a sports car needs is looks. If a sports car doesnt look like one it isnt, its just a big donk in something else. And good looks need flowing lines (which a number of sports cars dont have, they do tick every other box...) Flowing sleek lines where they dont just stop, and cross over. Where you can look at the car from any angle and see the same flowing line. If it doesnt have that, its a pointless car.
