yes they are complete bunch of idiots and every dealer comes up with his own new story and also mentality prepare you about the expenses which they may charge like he told me that make up your mind for around 8000 expenses max for that issue when i said why, he said your car is about to touch 50K so we can drain cylinder, check complete kit and tune from computer for that 3000 straight away and rest if we need to add any part that would cost extra like he said diaprams in kit needs to be replaced most of the time and blah blah blah.......
please be aware of them...
