CALIFORNIA (LOS ANGELES)

All about me


I am 19 years old from Los Angeles and know absolutely nothing about how legal matters work.

My story

Over a year ago my father's old Ferrari broke down. I had it towed to the nearest mechanic. Apparently the cam belt slipped causing valves to break or something of that nature. (A common problem among this model.) Price to rebuild the engine- $13,000 After some negotiation we agreed on $8,800. (Only half the motor was rebuilt)
As time went on the car was "fixed." Communication between the shop and my father was very limited. He spends most of his time outside the country on business. After a while the shop left a message to come pick up the car. For one reason or another no one was available to pick up the car. A few months pass by and the own of the shop informs my father that he will have to charge a storage fee.
I then decided to contact the owner of the shop. He informed me that he has signs post in his shop stating his company can charge a storage fee. ($75 a day). I decided to take a surprise visit to the shop to see if i could locate these signs. I searched high and low and no sign was spotted.
A month or two pass and my father goes to pick up his car with a bank check for 12,000. (The amount it cost to fix the car + storage chargers that were never agreed on)

After a test drive the car ran strong except for one problem. A grinding noise that was coming from the engine. The owner/mechanic told me that this problem will go away after the car is driven for a while (500miles).
~All deals were verbal~

What I would like to happen

Pay $8,800 for the repairs and receive the car

Questions
-Do I have to pay storage fee's that were never agreed upon? If so why? the car was never fixed completely.
-What can I do to get my car!
