the standard lip is attatched with adhesive tap and bolts. i'd get a body shop to remove it to reduce your chance of damaging the paint its mounted on.
you'll need to take it off for most aftermarket spoilers unless you have something particular in mind.
do you need to retake it all,
can you do the test on its own? if so how much ? just i've been driving tractors since i was 6 and reversing big trailers is 2nd nature for me, just wondering if i have to do the training as well. i do realise though the smaller the trailer gets the quicker it snaps its direction, and double wheel base is far more controlable than single wheel base.

never bought a car locally apart from my very first can which was 300 quid, i've bought from cambridge, stoke, harrogate, enfield, norfolk. 45 miles is the closest i've ever had to travel and that was just luck.
