Do you know latest version number?In Columbus (bob boyd) the one with 90k miles?
Best advice (prior to purchase) go to Rob in service and ask him to pull up the service records. so you know all repairs done there or warranty work done.
2) see if new modem put in to use with app
3) use an OBDII reader to see if there are any codes.
4) listen for noise while going over pot holes. (mine had this issue)
5) have them update the software to the latest version for the center console.(if not already)
I'm not giving up the 20s, I love it the way it sits...but, are there any good $200 tires for these, lol? And yeah, my feeling about this vehicle is that the first "owner" (lease) didn't take care of anything except maybe the appearance, no tire rotations, rode on brake rivets, (hopefully they at least changed the oil)... Then "a hero came along" and took care of her. I've been looking for a car for months, everything I've been looking at has had worse problems, or not as nice. I can't find a better MKC (especially a black Reserve) in Ohio with less rust or that isn't $2k-$5k more on average. Even if I spend $2k on tires, I'm ahead of the game...my co-worker just spent more than my down payment on rims for his 2021 Supra, I gotta keep up, lol jk.slight rough idle might be the side effect of a direct injection and the build up of carbon.
Cupping might mean the suspension is aged.
I suggest pickup used rims (smaller than 20) and that will help you find cheaper tires.
I def. am a Lincoln man for life. Already have an "MKC jar". My goal is owning one in less than a year... P.S. The salesman, Jim, at Bob-Boyd Ford in Columbus, Ohio is a straight-up guy, he's a used car salesman, but one of the less terrible ones. He had Bob-Boyd Lincoln deliver the car to my shop (27mi), let me drive it for 4.5 days, then got me a ride back to my shop, even when I didn't buy the car. And didn't pressure me. Highly recommend. (If you HAVE to buy from a used car dealership).Sorry to hear that. Hope to see you back at some point.
