Under the Colorado Motor Vehicle Repair Act (MVRA), you have specific rights to recover damages if a repair facility violates the provisions of the Act. Even if the MVRA does not apply, you can bring a breach of contract claim and possibly a claim for misrepresentation.
The MVRA requires repair facilities to provide written estimates, obtain authorization for repairs, and issue detailed invoices. Failure to comply with these requirements can make the repair facility liable for damages, including attorney fees. In your case, it appears the mechanic did not provide a written estimate or any paperwork, which would be a violation of the MVRA. The mechanic’s actions may also constitute a breach of contract if there was an agreement that he would repair the motor. An oral contact is sufficient, so it does not matter that you do not have a written contract. Given that he failed to perform the agreed-upon services and instead returned the motor in a more damaged condition, this could be grounds for a breach of contract claim.
Recoverable damages depend on the type of claims that are brought and on which legal theories you prevail. Among some of the types of damages you could potentially recover are the cost to repair the damages, the difference between the contract price and amount you end up having to pay to put you in the position as if the contract had been performed, attorney fees, and three times the amount of your actual damages.
This is just a general summary of claims and damages. Because the actual claims brought will depend on the facts of your case, please contact an attorney as soon as possible.
