These guys are complete crooks. During a recent service on my Chevrolet Cruze, they billed me 2000 for replacement of the window wash motor. Since I opted for their drop service the car was delivered to my home. No work was carried out at all. Also my music pen drives and jack were stolen. When I complained to General motors, they asked me to get the car back to the garage and that the pen drives were "safe" with them.
Avoid this crooked dealer at all costs.
