surely the garage can advise how to tax it?
It's the Carshop though, who are notorious for their excellent customer service.
Also, anybody had any dealings with extended warranties? Carshop have offered me one through the RAC at £25 a month. Seen others for around the same price and I'm wondering if it's worth my while getting one.
£25 a month is a bit steep! The company that does the 3 month warranty will send you through a cheaper quote at the end of the term to entice you anyway, but it's owrth getting some quotes.
