My personal experience only. I daily drive mine in NL. Is a 2016 with the headgasket recall done at about 24000 miles - ask ford dealer proof by the way. Now almost 78000 miles and no issues except consumables including clutch and flywheel. The car is stock 100%. Roads are good here in general so RS being stiff over bumps does not really matters but on bad roads you will jiggle a bit. I service mine at 6000 - 7000 miles. I let it warm up and cool down properly and drive it normal and hard sometimes for fun. I plan to keep mine forever so it is a collectible
Is a blast to drive, fast enough in factory specs, old school awd rally car mechanical/analog feel, looks fantastic, and for the rest is a Focus as you know it. Not perfect but awesome.
Do test drives as a final step in your decision process!
Good luck.
