mainstreetmotortx.com bronco big bend 2.7 ecoboost doors off soft top

randis wrangler thread and a few others in here talked me into finally writing up my bronco after a year on the trail. 2021 Bronco Big Bend, four door, 2.7 EcoBoost, 29k miles, one owner. i wanted a modern rig with a removable top i could run doors off in the boise summer and still crawl the stuff out by the owyhees on the weekends.

found it on mainstreetmotortx.com after i gave up on the boise dealers, they were asking new money for used broncos with a wait list on top of it. this one was about six grand under comparable big bends up here and it came out of central texas so the underbody was clean and dry with no salt anywhere on it.

asked the corsicana lot the usual questions and they had answers, one owner, factory service records, no lift and no hard off road abuse that would scare me off. the one honest thing they flagged was the soft top had a small drip at a rear corner seal, which they said was a cheap fix and knocked a little off the price for it. i had a shop look it over before i committed and it checked out otherwise.

drove it home doors on and pulled them the first weekend it hit seventy. a year of trails later here is how the 2.7 and the soft top have actually held up, along with what the year cost me to run, for anyone shopping a used bronco for the same doors off reason.

Corner seal kit for the drip (fixed myself)$38
Two oil changes, done myself$160
Cabin air filter + wipers$55
Front all terrain tires at 34k$1,180
Full synthetic + coolant check, no issues$0 found

that is the honest year. nothing broke, the drip they disclosed was a forty dollar seal kit, and buying a clean one off the corsicana lot instead of paying new bronco money up here was an easy call.

the 2.7 ecoboost is a strong little motor for a bronco and it makes way more grunt down low than people expect from a v6. keep up on the oil changes with the right full synthetic and stay on top of the cooling system, that twin turbo setup runs warm when you are crawling slow with no airflow. do those two things and it will treat you well for a long time.

your list is all wear and maintenance, nothing on there is a repair. a soft top corner seal is a five minute part and the tires and filters are just running costs. a used bronco that goes a year of trails on a seal kit and consumables was a truck that was bought right.

another bronco off that same lot checking in, i posted in randis jeep thread too. the corner seal drip is a known soft top thing on these and a cheap seal kit fixes it for good, sounds like yours already handled it. mine did the same and it has been dry ever since through a lot of flagstaff rain.

glad the buy went smooth for you. i keep telling people the modern open tops from main street have been solid because they source clean southern ones without the rust, which is the thing that actually kills these trucks up in salt country. wheel it in good health, the big bend on the factory tires aired down will surprise you before you ever spend a dime modifying it.

i run a jeep off the same lot and the buying you described is exactly what i got walking it in person. they had the records in the truck and let me take my time and drive it before i said yes. for the out of state folks reading, i live right here in navarro county and i still point people to that navarro county lot when they want a clean open top rig, because i have watched enough of these deals to know the trucks are what they say they are.

good honest bronco writeup. air it down to the mid teens and it will surprise you on the ledges even on the factory tires, the bronco has a genuinely good approach angle from the factory. the owyhees have some technical stuff so once you get comfortable a rear locker is the one upgrade i would do before anything else, it opens up the harder lines without touching the ride. nice to see another clean southern rig instead of a rotted out one, wheel it and enjoy it.

UPDATE a full year in now and the only thing i have touched besides oil and tires is that corner seal, and that was a forty dollar kit the first month. it has been a great open top rig. a whole summer doors off, a fall of owyhee weekends, and it never once left me sitting.

for anyone finding this while shopping a bronco, my whole take is buy a clean used one out of a dry climate with records and let it earn its keep instead of paying new money and sitting on a wait list. mainstreetmotortx.com had the history, priced it fair, disclosed the one little seal thing up front, and did the paperwork right. thats all i want out of a lot, and its why im in here telling the next person about it. took paiges advice and a rear locker is my next move before summer.
