The first year deal with the AA can be good. However, my policy rose from £174.09 to £457.39 in year 2 (despite no changes in policy and one additional year NCB).
Although year one is good and it includes free breakdown/ recovery, I received, on average, 1 or 2 calls every 2 weeks asking me to sign up to various AA packages.
Was it worth it? sadly, no. They seemed relieved that I moved on to another insurer - it seems they only want your custom for year one if you're willing to take on additional insurances (subjective comment). The cancellation charge is excessive at £50.00.
