Nope. Im just not a fan of installing them myself. I will do it if I have to. Smelly nasty job. Cost really does not come into it for me but seems to for most. That seems to be the argument for not getting the XR. I am simply saying its a poor reason not to get it.You bought an XR for the gears because paying for them to be done is expensive? Interesting economics ideologies, I'd love to hear more.
