Around where i live all you have to do is slip the attendant $40 and they will pass pretty much anything that isnt spewing out black smoke or buring 90% oil. But i would advise you to know if the shop will do that kinda thing or not... some will actauly get teh police after you. but if you know people who have done that at a shop with a certain attendant, bring them along and do the same. they wont refuse a bribe from you if another person they accepted a bribe from is standing right beside you.
