The Mustang has been a model of solid Ford engineering since the 2015 S550 redesign. The 2018-2020 GT models with the Gen 3 Coyote and 10R80 automatic are the most refined to buy used, while launch years bring teething problems.

The 2018-2020 Mustang GT with the Gen 3 Coyote 5.0L and 10R80 automatic is the most refined modern Mustang. Lowest complaint volume of the S550 generation.
Mostly. Early 2015-2019 cars had head gasket coolant intrusion on some VINs. Ford extended warranty coverage for affected units to 10 yr/150,000 miles.
It is too new for a long-term reliability call. Like any launch year, expect early software issues. Wait for 2025-2026 if you want a sorted S650.
A maintained Coyote 5.0L commonly passes 200,000-250,000 miles. The IRS and 10R80 are the limiting factors on later cars.
Yes, after the 2018+ calibration updates. The 2017 launch year had hard shift complaints but those were addressed via TSB 18-2275.
The MT-82 6-speed manual has had some shift-quality complaints but no widespread failures. The 10R80 automatic is the better all-around pick for daily driving.
