Don't feel to bad, My MR2 got it's last smog test and failed so off to the mechanic to give him a $200 donation. The mechanic simply adjusted my timing and charged me $150 for this. Then the thief says, if it doesn't pass, bring it back and we'll drop the other $50 in and I'll give you a waiver for the test. In our state the smog recheck was free, but I had to take it to a authorized smog mechanic to have it worked on because of the laws here. So, I got dry-banged for $150, but it passed and I Never have to get the car tested again. Both my vehicles are exempt from test, but not exempt from some nosey cop that says lift your hood, it's your lucky day. Modifications to the engine can cost upward of $2000 if and officer writes up the ticket. The laws have changed here in Washington State as well. From this point on, all vehicles from 2009 and newer must be equipped with California regulation smog devices. It's all about the money pretty much because if it was all about clean air, we be cracking Mexico's ass for their vehicles that run no smog devices. Mexico City being one of the smoggiest cities in the world.
