the 85SD with seats upgraded from a 90+124 would be my ideal. the flat design of the 126 pre85 (even in perfect condition) is a tad flat and uncomfortable for my tastes.
if you must stay in the 85 era, a euro 85300D would be a 124, and that'd be my choice...
better aerodynamics, and power, also better fuel economy and comfort in the seats with cloth material.
