Absolutely unacceptable this kind of treating car owners. Because i've been through such troubles with my VW i drive now a TOYOTA and i can see there a major difference. I can say now that TOYOTA is treating their customers with another attitude and more care even though i now don't let any mechanic or salesman or a minister to do anything on my car without talking intensively and precociously first any extra works and cost are going to fall! Please be always carefully and be precise with your declarations. Don't let them sell to you gold for coal it happens all the time everywhere .
