Sidestep:jonathan18: What is so special about modern cars that means the cost is so high? I read the post earlier that it relates to the modern features like stability control, but how exactly does this impact? (It's just this is depressing reading as I had intended to get one fitted on our car, but at those prices... Also I assume a non-official bar will void a new-car warranty?)
One of the issues with modern cars is finding suitable attachment points.
Most newer cars are built on a lightweight, engineered stressed metal shell, designed to crumple in an accident leaving an intact passenger capsule.
That's why manufacturers design their own towbars.
Some have flanges and tabs that mount to the weirdest, non intuitive places..
This is exactly why. You should also check the insurance requirement - dodgy workmanship, accident happen, there will be 1001 questions from the insurance company.
As both cars are brand new, I found it easier to get the original accesories - fitted by the dealer for warranty reasons.
