Well I ended up buying the G70 Sport 3.3 and for the first 244km I am quite happy.
My opinion on the styling isn't as strong as Sugarphreak's... I like the Stinger better from the back, and side, front is a toss up. I also really dislike the fake vents on the hood of the Stinger and the little vent on the side of the Stinger collects a ton of rocks which I didn't like. But overall both cars look good to me. Not best in class but not worst either.
Now the interior is where there is a big difference. The G70 has a way better interior, particularly seats and dash. And since I drive about 27-28,000km a year and mostly by myself, that is important to me. Way more than the exterior. The steering and handling is better on the G70 imo as well and that is worth it day in and day out. I would have loved the hatch, but aside from my golf clubs, kids hockey or taekwondo gear, I don't put anything else back there and those all fit fine in the smaller trunk of the G70.
Anyway, favorite parts so far: engine/suspension/interior - hopefully none of this gets old for a long time! Also I really like the Genesis connected app. I can see who many km are on the car, when the next service is, where the car is parked (spouse creep
) and start/stop, unlock/lock, honk horn, etc all from the app. One cool feature is the status monitor. It tells you if individual doors are locked or unlocked or open or closed. And it can tell you if the car is running, and if things like the heated steering wheel or defrost is on. Another plus is the welcome lights - as you walk up to the car, the mirrors fold out and project a Genesis symbol on the ground. Looks cool at night or in the garage. Also I like that you can fully turn off the fake engine sounds through the speakers (or choose 3 levels if that is what you like). Every car should have that option.
Negatives: they cheaped out on the door handles - lock and unlock are both via a button, no sensors, and only on the front doors. Even a Ford Fusion has sensor lock and unlock on all four door handles.
I am sure I will end up with more negatives as time goes on, but that is it so far.
Oh, and the delivery is impressive. They bring the car to your house in an enclosed trailer with glass sides and lights inside. Looks impressive and has your neighbors thinking "WFT" as they pull up, put pylons out and then back the car out. Service so far has been amazing and hopefully that continues when I need actual service done... I will post some pics later.
