The SW20 has more of a wedge shape, a shorter nose and more substantial back end, and the massive side scoops, where the eclipse is more dome shape and has the hood bubble and no side scoops. The back end is massively different where the eclipse has the big domed rear window, the MR2 has the flat vented deck lid over the engine and a concave rear window. While the eclipse has amazing tuning potential, doesn’t have the exclusivity that the MR2 does. They are both great cars though.
