A big YMMV, but....
Many people consider it money well spent to pay for, what could be considered the equivalent of a pre/post purchase inspection, a few months/miles prior to the end of your warranty. A Mazda dealer will, for a fee of maybe $100 - $200, give your car a thorough going over to find any issues that the can may have. The stated purpose would be for them to TRY any find areas that might be covered under warranty but may have not yet created a problem. Worn boots, warn axles, loose suspension parts, worn motor mounts - any non wear items that might need replacing. The dealer gets to charge the mfg for repairs (ching ching) and it costs you nothing. There are times when the replacement/repair need is questionable but they may still be able to mfg authorization. Again, the dealer loves it because you'll approve it because it costs you nothing.
