I don't know. I've always liked the look of the hardtop accessory for the current S2000. That picture above, the rear window is just angled to much to off-balance the long hood. Somehow, it just doesn't look right, IMO. I like this better:
By the way, 2.2L should ad at least 20hp to 260hp, if not 280hp (using the 140hp/L in the current model now).
