It really depends on what you want. Is a warranty extremely important to you. You'd be coming towards the end of a lot of 05 SRT-10's warranties being that it's not the 09 MY. You could always buy an extended warranty for them though. You could take pleasure in knowing how almost every mile was put on the truck. I wouldn't like that fact of owning a truck that hasn't been driven but a couple hundred miles a year. I think vehicles should be driven but that's personally me. The least I'd ever even think about putting on a vehicle in a year is 5,000. Any less I think you're asking for trouble. I think it's a decent deal for a new one, but if you're planning on driving the wheels to the ground maybe look into something "slightly" used.
