I sold my v2 rims recently for 1800 with new dunlop sport max tyres they came off my 20 plate nismo they had only done 500 miles, make sure you keep hold of the tyre pressure monitors as it will cost around 400 quid to replace them with genuine monitors
Hope they replace them for you, the warranty should cover mechanical and electrical for three years, the dealer you bought from should your transfer warranty, to your local dealer, thats what lookers told me in Newcastle
