Title really says it all, anyone know of one that they have used and trust outside of the Stevenson Mazda dealership who just aren't proving very cooperative or useful? It all relates to a matter being kicked around on the Discussion Group forum about exhaust smell in the cabin.
Thanks

 

I usually only go to the Stevenson Mazda dealership cause I don't trust other mechanics. Not sure if the mechanic would know much about rotary engines.
