Long story short, I managed to swerve into a parked van last night, and damaged the bonnet, wing and light cluster on my Lolvo. From a cursory look, it's not going to cost more than a couple of hundred to replace these (i'm not fussed about re-spraying etc. at this stage, just need to get it back on the road ASAP for lowest cost). Is it legal for me to do these repairs myself, or do they need to be done professionally/certified/etc.?
