It seems very minor if you're happy with the rest of the car, I'm sure any competent garage would be able to sort it out for you if it's not something you could sort yourself. I'm sure some fellow owners from around your area could advise you on a good garage if needs be.
I wouldn't let that stop me buying a car I liked however, how are the brake pipes since the advisory? Have they been changed etc? As that could cost a few hundred to fix.
