Well got myself a Thule tow detachable bar & fitted it, ordered the plug n play electrics from Cheltenham Jeep for an unbelievable £25 (cheapest jeep part ever?), which turned out to be the wrong ones when I went 30miles to pick them up , the price then went upto £60 before finally settling at £130 all because the dealer didn't know much about Jeep parts, the car has been off the road for 5 days meanwhile (bumper off etc).
To be fair the parts manager discounted it & the other service items I wanted to cost, but it meant it all worked out more expensive than wouldve been to have it pro fitted.
