50k cad ($41k US) for this level of car--assuming you are shopping for driving qualities more so than infotainment/tech--is a ridiculously good value proposition. I find it hard to wrap my mind around the combination of refinement, performance, comfort, space, and practicality, and how much you would have to spend for something comparable in those regards. Audi S5 sportback, BMW 440i Grand Coupe, Mercedes C43, maybe some of the crossover versions of these, and you'd have to option them up. Each of these have pros and cons compared to the Stinger, but the point is they are in the ballpark in terms of overall experience.
Yes, you can find deep discounts on the Germans at times, and you can also find fire sales on the Stinger.
