I'd pick the SRT just because its blue, but thats just me. The mileage really doesn't mean anything to me. My Limited roadster has 70,000 Miles on it now and runs like a champ! I personally don't like vehicles with extraordinarily low mileage because either way it means it has sat for periods of time. I would be concerned with problems like varnish in the fuel tank and lines, which can occur after as little as a couple of weeks of sitting stagnant. Seals also have a tendency of drying out when they don't get the constant splash of oil required to keep them properly lubricated. After extended periods of time the oil film on parts can become too thin to properly protect components on first startup.
Just my $.02 from my mechanical experience.
