We have an 05 Deville in our fleet with 65,000 miles. We saw a leak under the car and carried it to the dealership. They called back with a list a mile long of what it needed and I need advice as to what is an immediate need and what can wait. Power steering pressure hose, transmission output shaft shield,transmission pan gaskett and 2 valve cover gaskets for a price of $ 1,817.00. oil pan and spacer plates rear main sealand front cover gaskets for a price of $ 1,475.00. This car has been well maintained since purchased new and I just can't believe it needs all of these things. The wholsale price of this car is only a couple of thousand dollars more. Any help would be appreciated.
