no, the corvette and cobra wouldn't really get a ton of attention because the corvette uses dated technology. It's suspension in sub-par (ohh no, time to get out your magazines kiddies!!!) The z06 suspension has absolutely nothing in common with the c5r. the c5r has incredible linkage and uses a significantly better design for damping. And i am assuming you're talking about the mustang cobra... that suspension is a joke and the american iron guys will agree with me.
But sure there is an appeal to won a corvette or cobra because it is rare and would turn heads.
