Especially since we have an extra special exhaust system.

About the door locking thing. My girlfriend's RAV does this. It is actually annoying because if you unlock the doors to put something inside and don't make it there in time they lock again. Since I don't have a key, this stinks and I have walk back and ask to have the doors unlocked again. It only does it if the doors were locked in the first place. If you leave them unlocked they stay unlocked.

In my area I wish the doors would auto lock after a few minutes if they were unlocked and the car was shut off without locking the doors. Of course I should just make sure my doors are locked instead of having technology do it for me. I just find it hard to make sure because if you lock them and then test either front door it unlocked (obviously when the FOB is near).
