Brand new here, could barely figure out how to post this! Have 03 WRX wagon which needs new catalytic converters (live in MA, must have for emissions). Car has 125K miles on it. Trusted mechanic is hesitant to have me spend the 1K and upwards on the repair. Advice needed! Thanks in advance for any responses. I know NOTHING about most of the things I am reading on here so please be gentle.
