Dont understand why Trading standard not Getting these big groups done for scams.Never Trust Their AA Assured report. Bought an assured Ford Fiesta 14 plate 35k on the clock stating coolant level needs topping up.topped up the coolant with help of one of BCA staff on the site before leaving BCA site .After 2 mile run car fully heated up. Went back to Bca assured team they refused to take the car in or cover the damage as the trick was stated in the assured report coolant level low,while they should have sold this vehicle as non runner head gasket problem.Ended up putting up new engine 2k. Stay away from this scam they sell you as AA & BCA Assured vehicle ***
