You can set these cars up to flog a miata on a road or AutoX course every day of the week. You just have to pull your head out of the 70's and use the MUCH IMPROVED modern day technology that's available for these cars. Of course, doing that will violate your delicate sensibilities of '70's style because it means using tires that aren't hockey pucks and suspension geometry meant for radial tires.
You want a car that handles like a barge and looks like it was modified by a coked out Hippie, be my guest. But that doesn't mean you have to force your closed minded, outdated opinions on the rest of us just because you'd rather have a car that "looks right" to you than one that actually performs well.
