How easy is it to fit a detachable tow bar to my e53 2006 X5?

Getting quote of £535 supplied and fitted and the same one on Ebay is £200!

 

I fitted a westfalia detachable towbar to my old X5 a few years ago, it was pretty easy to be honest and the supplied instructions were very clear. get one with the dedicated wiring kit, its plug and play and wont throw up any warning lights

 

did mine last year got it from here

worked out about £270 with the BMW X5 Dedicated Electrics

quite easy to do only takes a few hrs all plug and play and even turns off the parking sensors when you have trailer on

 

so i wont need to cut any wires etc, its already done. everything is just plugs, i can handle the tow bar but i dont have a clue about electrics!

 

I also bought mine from pf jones, no cutting of wires with the dedicated electrics kit, its really straight forward

 

Thanks guys, will order one from them then.
