Hi folks, After some advice for a rear mounted carrier, I drive a Mondeo 5dr hatchback (with standard rear spoiler) '99 model. Some websites state that a carrier & spoiler = no no? I was looking at the Thule Freeway 968, but to be honest I have absolutely no idea if it will fit well. Whats recommended, high or low carrier (I know the advantages/disadvantages to both in terms of drag = fuel consumption or lower = additional number plate board etc). Any advice would be mucho appreciated!
