Have you driven a Ford Fusion Sport?Next time I drive a G70 I'll try the Sport mode. The Comfort mode just felt so "right" that I didn't feel a need to try a different Mode. I usually use Sport mode in my Edge for the improved throttle response, because in Normal mode it's honest disappointing. In it, Sport mode is for me a necessity.
I have the Livernois tuner for my Edge, but it's not transferrable to an ST. I already checked on that. I'd prefer on my next vehicle to not use a tuner, and instead keep it stock. The ST without a tune isn't going to feel much different than my Edge Sport, acceleration wise. Not so with the G70. It pulls strong and on the street it's plenty. The Edge has more storage space but I'm the only one that drives it and rarely use the space I have now. So an SUV isn't all that important for me, but I do agree overall the Edge is more practical. I just have a problem spending that much coin on a vehicle that lacks so much of what the G70 offers. The Challenger wouldn't be practical at all in the winter, so that's a big negative. Driving the Scat Pack in good weather would be a hoot, for sure. For me, the G70 fits in-between the two. Not quite as practical as the Edge but more practical than the Challenger Scat Pack.
I've got time to make my final decision, so that's a big plus. I'm not rushed in any way.
I can only tell you that the driver's door felt very solid when I closed it, and the car overall felt really solid. I would bet the steel thickness is greater in the Genesis. Here is a blurb form the WSJ about another Genesis model. "Hyundai has also put a lot of equity into high-strength steel, as compared with aluminum construction; and the numbers look good. Hyundai claims the Genesis chassis torsional and bending stiffness now exceeds that of a BMW 5-series."
