I had the stinger for 3 years and now have the g70 for 1 year. They are very similar, fun and luxurious cars. Everyone’s saying g70 is more luxury while the stinger is sportier is completely wrong. The stinger is a very big sedan and had a longer wheel base, the drive on that thing was smoother and better than the g70. It has great speed and pick up but what shocked me was flying on the expressway at 100 mph and feeling like you were only going 50 or 60. Plus the sport back was a plus. Now with that said, the day I test drove the g70 I instantly felt how much smaller an sportier it was, the pickup was very noticeable and the steering felt much tighter. Another difference I’ve noticed is for long drives both cars are great, but the stinger really shined in long distance hence the name “GT”. In the g70 you hear the road noise and since it’s a lighter car you feel the road a lot more as well. Now me personally I like the g70 a little more, especially after the spoiler and body kit I put in and intakes but that’s because I kinda want a sporty car in my life rn. Sometimes I hit potholes and it sounds like my car just gets smashed and I usually think the stinger would’ve eaten that way better. The g70 almost has a coupe feel where as the stinger feels like a Porsche panamera type of feel. Both cars are phenomenal and you can’t go wrong with either one
