MINI of Las Vegas

Sorry state of affairs. I went to the service station with several problems in my car which i bought from the same dealership 3 months back. Right from the first moment the staff was defensive and more than helping the customer they were looking for reasons and excuses to run away from any liability. For anything you show a problem they have an answer you better go and get it fixed at Lincoln dealership it would be easy for them to fix. Catch is No Lincoln dealership that is covered by Autonation in Las Vegas. If so was the case can someone answer why the hell they sold an extended warranty in first place promising you will be completely taken care of. If there is an electrical problem, they say they don't have it covered. If there is engine start problem, please replace the battery (and later you will be informed that sorry we don't cover batteries so please pay ~$500). Dealership did mention they did put a brand new battery while selling the car 3 months back. So apparently even that was not true. Later labor will also be charged separately. It wouldnt be wrong to say they smartly trick the customers with rosy promises and later nobody bothers. Within 3 months of buying the car from the same dealership I have like 5 problems in the car. Out of 5, they fixed just 2 problems and charged me more than $700 in total. God bless Autonation and such dealerships.
