I am in the car business.
Trust me, you got off cheap.
Do you still have your first born son or did they take him too and you just aren't telling us?
Seriously, it does seem as though you were, ummmm, ripped off.
Perhaps more details about what it took to install the heavier guage wire to the starter...was it just from the solenoid to the starter?
What do they mean by- "Flushed the
oil cooling system"....there isn't an
oil cooling "system" that you would need to flush...it is called "draining the
oil" by most people.
How much did they charge you to build the engine - $35,000?
What did they say when you asked them for an itemization of the charges....?
As far as them test driving the car - that should show up as a credit on the bill!
