The only time I've ever noticed "cowl shake" was going over a road that looked like an Olympics moguls course. Yes, convertibles are heavier than coupes and don't handle as well at the limit. Are you going to notice the difference between a coupe and 'vert in daily spirited driving? Probably not as much as an IRS-equipped car (Camaro, Challenger, Explorer, Expedition) versus a live-axle equipped Mustang.
