I paid like $150ish for both of them. $80 OBO takes them. I've had them for a year but they were only installed for maybe 3 weeks. They come with everything you need to mount them...which is very easy. You can use the stock mounting points for most cars.

They arnt that purple.. they are a nice bright blue. Oh and for some reason the button to release the belts is red; not blue.
