Hi--It seems I've found a rust free 240 wagon in my price range and am deciding between a 91 and 93--both 5 speed. All other things being equal except for interior color which do I want and why? Both have running air con and most all other options are working on both. There is a price difference in the 93 being offered for more. Is the 93 better just because it was the last year made? Is it significantly better? Will the air con last longer on this one? Will the 91 have the same gusto in a few years? Both also have the same mileage within 1k miles. I would be satisfied with both but am buying from photos and descriptions only as they are far away. Both have been highly maintained by certified and very qualified Volvo mechanics for the last 15 years. This is a good dilemma to have but I can't decide! All you Volvo gurus out there give me some advice. What should be the deciding factor?

Thanks! Monique
