Ford Mustang 2017 Problems

Demos are not generally abused; they are mostly driven normally with reasonable care, often under the supervision of a salesman.

You’re worried unnecessarily, and besides, the car will still be covered by Ford’s warranty if it happens to have a problem.

Ford says that the Mustang has met all relevant safety standards in America, which they say demonstrates that it is a safe car. But the Mustang is now a relatively old model, having gone on sale in the USA in 2014, and it doesn't have some of the safety features most other cars have. While it's lacking in some areas, it's not an inherently unsafe car, it's just not as safe as other cars that have a 5-star rating. Ford says the 2018 model will have features such as AEB, so perhaps wait for that.
