Extra parts

So a spark plug job turned into a nearly 4,000 dollar bilking, and you still don't have a running car? As to the clutch, you would need the services of another mechanic to determine what was replaced (if anything). If you determine you were ripped off, then you need to have the following: the original quote and invoice from the first mechanic stating what work he allegedly did; a statement from another mechanic and photos showing what was actually done to the car; at that point you can demand a refund plus compensation, file a complaint with the BBB, file a suit in small claims court (although this court limits amount you can file claim for), or file suit in regular court, and finally take your case/complaint to your state's Attorney General's office. (The AG is a good resource to go after scam mechanics). $4,000 and 4 months for a clutch is just insane, you got ripped off big time. Time to document everything and seek help.
