I have only had for short time. But so far I just love it. It's hard to get used to an SS having 4 doors but I like the emblems, reminds me of days gone by. I traded in a crew cab dualy, so this is of course way more fun. I read reviews here before I bought it. And I have to agree about the wind noise and torque steer. But I bought it and like it anyway. I got almost 28 miles to gallon on a three hr. trip. That was at 70 with cruise control. I liked the steering wheel controls in my pick-up ('04 Silverado) better than the switches on the dash in Impala.
The 300 hp. The ZO6 heads. The sound of the exhaust. The mileage is acceptable. I can't tell when the engine switches from 4 to 8 cylinders. That is amazing.
The front seats could be better. They are too flat with little side support. Cup holders could be better. Something that is taken for granted in other cars. Really should be rear wheel drive. But in reality, I will probably appreciate the front wheel drive when it snows.
