I have found that the driving dynamics between the coupe and sedan are different.
The sedan to me is actually more tossable and just seems to be a tighter car then the coupe. You also sit more upright in the Sedan which gives you a better view of the road.
If driving dynamics is your most important factor, I would go with the sedan (without the folding rear seat) over the Coupe. It provides an extremely solid car, for some reason, the sedan feels more agile and seems to take the curves a little more confidently though there is a tiny drop more body sway due to the higher center of gravity.
The Coupe on the other hand is sportier looking no matter what anyone says, it's just the way it is . . . . coupes are sportier than sedans . . .
I find the interior of the coupe to be more comfortable because the b-pillar is not in your way and the drivers door armrest is longer. It feels like your driving a bigger car and as far as the driver is concerned, there is more space. The Coupe sits lower which makes the handling feel flatter and there is less body sway (though we are talking very little difference)
If I were going to go and buy a new 2002 today . . . I would go with the sedan and that is strictly from a driving point of view, it drive's slightly (and we are talking extreme's here) better than the coupe
If looks and image were a major factor, then the Coupe is slicker looking and definitely gives off a sportier image.
Also, let me add . . . this is a viewpoint under a microscope.
Overall, they are both incredible cars !!!
