a 'lot' of the problem lately are related to the newer cars having computer monitored 'everything'...a mechanic no longer looks at and understands most of of it- he hooks up a diagnostic gadget and believes what it tells him, and like your computer, all the answers may not be covered.

I have a Dodge van that simply doesn't have a certain part..(some transmission solenoid)...but everytime there is any motor, fuel, transmission problem, this missing part shows on the readout as BAD...and they run in circles for hours until someone makes the right phone call and determines that there was a mid-year change, and they have to look somewhere else... **VAN STALLS AND COUGHS**..they consult electronic toys for days, until someone thinks to look at the fuel filter...clogged!!...(and this is the dealer!)

so, like spaw says, you have to be careful and ask around...(I found an old Hungarian refugee and his son who are 98% honest and 89% good....an indication is that the place is ALWAYS full and running behind...but they are always nice, caring and fair.)....hope you all have similar luck.
