Does the G80 have any interior odors? I used to drive an XC60, and it didn't have any smell at all—the cabin was very comfortable. However, Volvo's soundproofing isn't great. I took a ride in a car-hailing service today, and there was an indescribable odor inside the car. Not sure if it was a plastic smell or something else, but even though it was faint, it made sitting inside uncomfortable. I don't know how the driver tolerates it. I test drove the G80 and noticed a bit of a smell, but it wasn't unpleasant. It definitely can't compare to a new Volvo. I'm curious if the smell will still be there after one or two months. With my previous XC60, even after being parked under the sun, there was no noticeable odor inside. Any G80 owners care to share their experience?
