Query on Ford Fiesta 1.25 specifications?

Am inheriting an 07 Reg Fiesta from a deceased relative. Trying to get a probate valuation from Glass's website. On entering the Reg No it asks me to choose between a Fiesta 1.25 2006.5MY Style Climate and a Fiesta 1.25 2007.25MY Style Climate. Can't find any info on ".#MY" specifications. What is the difference and is there an easy way to tell them apart?
