Re: looking at buying a 6.0 is 215k miles to many?
The miles are ok, not great but ok. It means that truck hasn't spent an entire lifetime in the shop which is good news. However you might want to find a different place to purchase a truck. Those prices are insane, in wyoming where 6.0's are not popular I paid 16k out the door mind you for a fully loaded 07 f350 crew cab lariat, and I mean fully loaded with only 96k miles. The trucks you describe would be between 8-12k here. If you're 17 and drive a lot like any 17 year old I would try and get one with low miles. Just my opinion, and screw the friends they don't pay your bills, get what you want and let them figure out where to sit.
