The V8 was impressive stuff then. It still is now. There's no question the Mustang moves with the best of them and still handles like its on rails. Ford's build quality on its convertible is unprecedented - a tight, integrated feel that lets all that muscle flex and breathe. There's plenty of lateral grip and steering feel is solid.
Comfort is a bigger problem.
No matter how many times we adjusted the front seats, it never got better - more the equivalent to driving on a bar stool. The rear seats weren't much better. Road noise and rough pavement can also make the ride uncomfortable, especially with a rear suspension that still includes a solid rear axle. But this is a Mustang, not a Bentley. You are excused for not associating sun-drenched driving with a Mitsubishi, much less a Mitsu with two names going for it.
