Re: Grand Cherokee SRT offer...
I passed on a demo, and bought new. But there were 10k miles on the 2014 demo, and my new 2014 was only $3k more. No brainer.
Look it over really well and see if you can have it for an extended test drive. I had the used one for a week and finding french fries under the seat was the last straw.
Another thing to think about is the cost of replacement parts that are already getting used up on the used one, like tires and brakes etc.
