Hey i bought a 2008 nissan altima and the door needs to be replaced, how much do you think it is for a new one, including the installation.

I just bought a 2008 Nissan Altima with a cvt motor. There seems to be a vibration though. It’s on and off. The dealer that I bought the vehicle from told me it was normal because of the cvt motor. Everyone else i’ve spoke with disagrees.
