Well it depends on which year car.
I owned a 97 +4 and now an 06 3l Roadster.
The +4 was a short door car with a Librands manifold and sports exhaust plus a panhard rod. The Roadster is stock but has upgraded shocks anti tramp bar and stock panhard rod.
The Roadster has stunning acceleration vs the +4 especially at over 3500 rpm. It is a better grand tourer which is why I bought it.
Hope that helps
John
