Our mini is now out of M.O.T, and in need of repair after Dad was let loose with a screw drive while i cleaned behind the arches

My question is - should we look into spending the extra money on genuine panels rather than non genuine with possible fitment issues?
the panels we need are both rear quaters, both door steps, rear boot hinge repair panel, boot floor, both wings and front panel - possibly A panels depending on condition when we start stripping.
all panels if genuine we will get from mini spares - but as they don't ston non genuine rear qtrs i was looking at these from classic car parts direct - http://www.classicca...:38KEY:1340PAR:

Any tips on what i should go for?
Thanks alot - Mike
