I think you are facing the same issue I had before switching over to the Stinger. I, like you, had nothing but nissan's and Infiniti's, loved them. When the Stinger was announced it caught my eye and sparked my interest on the brand. I was skeptical at first since the brand had a not so good reputation before, but after doing my research and seeing all the improvements in every department (interior and exterior design, performance, etc.) and the amazing warranty they offer I was half way convinced that the Stinger will be a tough candidate.
Fast forward a few years and the Stinger is now available in Korea and the reviews start coming out. Everyone raved about the car and praised the brand for creating a very serious contender to the big German boys and a very solid alternative for those that want all luxury, performance and tech features the competitors have for a fraction of the cost. Shortly after I received notice that a K-spec Stinger was available for show only at a near by dealer, I immediately made my way there to check it out. Needless to say I was extremely impressed by the looks of the exterior, the interior had the quality and design that of its German competitors. At that point I was just waiting for the Stinger to be released in the US, and asked the dealer to call me whenever they receive the first GT model.
The big day came and got a call from the dealer claiming that they had just unloaded a black GT2 RWD and that it will be ready in the afternoon. I was there that same day, test drove it and it was everything and more than what I had expected. Performance that rivals and in some cases beats cars in the same category at twice the price...Check....Features that are sometimes missing or not found on some of the cars on the same price price point.....Check......Luxury ride with enough grunt and power to surprise those when they least expected.....Check. To top things off you don't see many of these on the streets so wherever you go you will have someone trying to figure out what in the world is that beauty and who makes it, the best part is looking at their faces when they find out who makes it
I ended up getting with a Snow White Pearl GT2 RWD and do not regret switching from a big name brand to the underdog. Photos for reference, she looks a bit different now
