The first ZDX tried the coupe-SUV formula long before it became common, pairing a 3.7 V6 with a 6-speed automatic and SH-AWD. Its rarity and styling are the obvious talking points, but the real used-car logic is much less romantic: it is still a heavy, complex Acura that must be bought on service quality.
A good ZDX should start cleanly, shift without weight, stay quiet at the rear axle and feel coherent despite its unusual shape. Poor examples usually betray themselves through skipped rear-differential service, tired transmission behavior, suspension knocks and expensive body-specific problems.
