I have no experience between the 5.4 vs. the 6.2. Besides whats on paper, HP, gas mileage, etc, what is the issue with getting a 5.4? Is it less reliable? This 5.4 was a pavement pounder, a guys second car with 98k miles over 12 years. Its clean with no rust. I have a good deal on it, sub $400 a month payment. I was planning on getting some used fox shocks to be able to rotate them out when the other is getting repaired but besides that I thought the 5.4 is solid. If you guys think its better to wait for a deal on a 6.2, for sure let me know. I don't want to make a big mistake.
