I was driving a 46 year old Triumph Spitfire 1500 on a motorway during a severe heatwave, When I left the motorway the cooling syatem erupted leaving me with no cooling system. I limped 2 miles to my daughters and then added 4lires of water. The car then started but I contacted the AA because I had a 26 journey back home. The AA came to my car and although unable to identify the cause of my brakedown, they escorted me all the way back home. An excellent service from a very pleaant and patient team.
