Rented one for 18 hours. Really wanted to try it despite not having XM.
First of all, it looks .....in'. It's got a menacing profile, and those bright LEDs across the back are magnificent to view. They turned my head the first time I saw them, and I saw the same thing happen to others that I drove by.
I liked the standard touchscreen, but it's like putting an iPhone screen on a garage door. It looked tiny and out of place.
I liked the engine power, and handling wasn't bad.
Visibility was much improved.
The nose bottomed out coming in and out of my drive way. It did the same for my old Camry as well; one of the reasons I now roll in a 4Runner.
Trunk space was adequate, but I had to get a little creative for 2 checked luggage and a carry on.
Just like the new 300s, the new Chargers are a great improvement and has been taken off my DO NOT RENT list.
