My car started bucking and losing speed after driving every 50 miles or so on the highway 2 weeks back, to the point where after a minute or two it’d be dead in the road, going back to normal once it got about a 30 minute rest. I brought it to a mechanic, who said it was because my catalytic converter was too old and replaced it for me. Along with diagnostics and labor it came to a grand total of $326.27. Unfortunately, this was not the solution, as the problem continued. I brought it to another mechanic whom my dad recommended as a knowledgeable and honest man. This one did a diagnostic, didn’t know what was wrong, and guessed that it might have something to do with the sensors on the car. Apparently, his guess was right, as after a clean the car runs perfectly. He was even kind enough to give the diagnostics for free, because he wasn’t sure if he was correct. So, the correct solution cost me less than $30. So my question is, what is reasonable to demand as a refund from the 1st mechanic? Everything? Under the circumstances, was his guess logical?
Also, unfortunately, I seem to have lost my reciept for this transaction, will this vastly decrease my chances of getting money back? I was thinking he’d have the transaction in his records, and if that doesn’t work, I can show him bank records of the transaction.
Finally, not sure if this matters, but my car is a 1996 Geo Prizm.
