I'm going to assume the greater majority of those 300k miles were highway miles? And I don't say that to lessen the impressiveness of it at all, I mean it purely from a logistics standpoint of 30K miles a year. I drive 20k - 25k annually and at least 15K of those is highway (I travel a fair amount for work).
Wow.... I hope mine goes that far! Most of my miles are put on fast. I guess that's highway..... most times. I think it is all about the maintenance. I am very impressed with my 2009. Built like iron. That is a hell of a lot of fuel in a V. Say 13 Mpg per gallon. That would be 23076 gallons of High Test at 3.75 per gallon. Would be 86,545.00 in fuel. Incredible!
Good work! Just breaking in! Kudos! Do we hear 400,000 ???
OP, are you the original owner? I see you joined the forum in '15. If not, how many miles when you got it?
What's the average cost of fuel per gallon where you live (Louisiana) ? If you were in CA, that would be pushing 7 figures!
