Welcome, I have two 2005/6 cars. one has no parking sensors but folding mirrors which are colour coded, the other parking sensors and but no folding mirrors which are chrome. The good thing is that parts are so often plug and play and so I got a car the same colour off ebay as a spares or repair and took the rear bumper and parking sensors from it.
I have heard it said that near the end they just fitted what they had
winters coming, if you have not got one get a fuel burning heater (FBH) it will make a nice edition to the car
