I won a gift certificate off a radio station that is good for 4 Free Lube-Oil-Filter services and a Comprehensive Vehicle Inspection during each visit. This certificate expires December 31/2009. Im asking $ 50 for it or make me a offer. Again this gift certificate can be taken to Master Mechanics for a free Lube-Oil-filter services up to 4 times. The same car has to be used and you have to use the gift certificate at the same Master Mechanic. If you need more info and might be intrusted let me know thanks. Also if you want to see where locations are go to www.mastermechanic.ca and click on locations.
