£35 for a wiper is a piss take too. You did the right thing going to a main dealer but be realistic as well,the cars 2005,there could be a slight amount of surface rust on those brake pipes and now the garage want silly money to replace "all" front to rear pipes.
I'd be looking into getting the suspension and electrical work done on warranty and accept the rest as your own problems but if you shout loud enough and bother them they may just take it back/repair it all.
I always fancied one of those having been in one brand new which felt really rapid but they seem to have so many issues its unreal!!!!
