Hi Pete,

As per Elwood, the official grouping for the focus ST from the Association of British Insurers (ABI) is 17, or 15 for the older ST170 model.

If you ever need to find the current ABI recommended grouping, which forms the starting group for most Insurers until they gain their own experience with each individual vehicle go to this link (see search field on right hand side of page):

Insurers do re-rate all respective vehicles once they gain their own data for claims experience, but the ABI scale is normally adopted by most UK Insurers as a starting point.

Kind regards

Tony
