Does the Unfair and Deceptive Practices Act apply to a used car sale by a private seller?

Question Details:

The car fails to pass admissions because the check engine light would not light up when all the other lights are suppose to. Later I found out, only that light was tampered with and can not be fixed. It will be impossible to pass admissions with out that light inoperable. Therefore, I cannot register the car in my name. Can I legally get my money back from the man who sold me the car, who is also a mechanic? Important Notice
