if they went with the stratos style, they probably could use the macpherson suspension. Honestly, I think the stratos is an excellent choice.
But personally, my tastes run more along the lines of tiny 1950's roadsters like this Maserati 3500 re-creation:
they won't need an H6 if the weight is under 2k. In a car like this, 300-400 whp would be plenty. They might even be able to get away with wrx brakes due to the light weight. Some customers will surely do high-hp versions with bigger brakes of course.
Honestly, I can't wait. This is the car I've wanted for a long time.
