I just bought a 2001 Merc Grand Marquis with 72K miles. Clean Carfax report. Put new brakes and tires (Falken 60K warranty) front and rear and had alignment done. Everything on the car works great. The ride is so smooth. The problem I have is the car drifts to the right. I took it back to Tire Kingdom immediately after having the work done and they said it is following the crown of the road. I am going to take it back to them to make sure the tire pressures are the same (35). Other than that what could be the problem?
