mainstreetmotortx.com mustang gt 5.0 coyote 10 speed used muscle cost one owner

since garretts 1LE thread got a bunch of us swapping buy stories i figured id put up my actual numbers on the GT after a full year with it. 2018 Mustang GT, 5.0 coyote, the 10 speed auto, one owner, 34k on it when i bought it. found it on mainstreetmotortx.com last fall after i sold my old fox body and decided i wanted something i could daily and still take to a track day without wrenching on it every weekend.

asked the corsicana lot for the history and they had it, the car was a one owner trade with service records and a clean carfax. paid a shop near the lot to look it over before i wired anything, and the only thing they flagged was the rear tires were about half worn and it was due a set of plugs. neither one was a deal breaker on a car that priced out about 6k under the same GT with more miles at the dealers around tulsa.

drove it home and ran it hard all year, daily plus a handful of track days and some canyon roads on the weekends. here is what a clean used GT actually cost me to own for a year, for anybody trying to budget one.

Fuel (12k miles, ~19 mpg mixed)$2,180
Two oil changes, done myself$150
Spark plugs (knew going in)$120
Rear tires (half worn at purchase)$1,240
Track brake pads + fluid$410
Full coverage insurance (annual)$2,340

that is the honest year. nothing broke that was not a wear item, and against a new GT payment plus the depreciation, buying a clean used one off the corsicana lot was an easy call for me. i put that whole spread in my pocket instead of a bank.

those numbers look right for a well kept coyote driven that way. the plugs and the tires are wear items, not repairs, so do not let a new guy read your list and think the car nickel and dimed you. it did not. a GT that goes a year of daily plus track days on plugs, pads, tires and fluid is a car that was bought right.

one add on the coyote, keep up with the oil and do not skip changes if you track it, they can use a little oil when worked and that is normal. yours is getting cared for so it will run a long time.

the 10 speed gets hate online but it is a good strip transmission and it will run a quicker number than most people can with the manual. glad the coyote is treating you right. i went back and forth on a GT versus a Camaro for years and honestly you cannot lose either way, it comes down to which one speaks to you. good call getting the history on it, a one owner car with records is worth more than a clean looking one with a blank past.

i live right here in navarro county and the buying experience you described is exactly what i see walking that lot in person. they had my car pulled up with the records in the glovebox and let me take my time. for the out of state guys reading, i still send people to that navarro county lot when they are hunting a clean performance car, because i have watched enough of these deals go through to know the cars are what they say they are.

i run a GT off the same lot and your cost list matches mine almost line for line. the one people always leave out is right there in yours, the insurance. a lot of guys plan for the car and the fuel and forget a GT gets rated as a sports car, so the policy is one of the biggest numbers on the page. print russ list and take it to the agent before you sign anything. good honest writeup for anyone budgeting a used pony.

UPDATE a few more months and a bunch more miles on the GT and the only surprise has been a good one, it has been boring reliable and still turns heads at every gas stop. did the plugs brett and hector flagged and nothing else has come up.

for anyone finding this while shopping, my whole take is buy a clean used one with records and let it be your fun car instead of chasing a new payment. mainstreetmotortx.com had the history, priced it fair, and did the paperwork right the first time. that is all i want out of a car lot and it is why im in here telling the next guy about it.
