Don't have a Stinger, yet, but have been doing a ton of research. My present drive's (2016 MB C-300 coupe) lease is up this August, and my other car is a 2013 ATS Lux. My previous cars, all bought new and each kept for around 10 years, were BMWs, 2002 325i and a 2005 Z4. As I'll be keeping the ATS as I consider it to be my BMW, handling wise, I never considered a new BMW (they just don't handle like the E46 become ATS.) BTW, I'm 80 and never had "nice" cars until I retired 20 years ago. Anyway...
All the cars I looked at were RWD. I was first interested in the Audi Sportback as I never had an Audi, but aside from cost when loaded, I just felt that the car was too conservative looking for me. The next car I looked at was the Alpha Romeo Giulia TiSport. Really liked it, but smallish back
seat and didn't have enough bells/whistles. But then the 2019 Camaro 3LT V6 caught my eye as it had all the bells and whistles, was comfortable and drove well, and cost quite a bit less than the Giulia; but as its rearward vision was very, very bad, I went back to the Giulia (a very fine driver's car.) However, V6 engine's were starting to take over from 2L turbos, and then I turned to the Stinger GT2. I really like coupes and small cars, but as my friends were having trouble getting in and out of my ATS and would have the same negative experience with the Giulia (remember we're old farts,) I started considering the GT2. It certainly would be fast, sporty enough, comfortable, good looking, and the back
seat would be more accommodating than the other cars. However, now with the
G70 Prestige in view, I do have to take a closer look at it compared to the GT2. I happen to like the exterior of the GT2 better and I also like the GT2's dash better...but there is something about the
G70 I like, but can't explain. BTW, getting in/out its back
seat wasn't as bad as I thought it would be, but it is easier in the GT2. The GT2's hatchback is not a necessary condition as I don't really need the room. So, it is between the GT2 and
G70, and I suspect that the final decision will rest on competitive costs???
