Motorist Mike Harrison is still driving his first car, 54 years after paying £150 for it. The 74-year-old was 20 years old when he bought the black Bentley sports coupe in 1956 after passing his test. Now it is one of only three left in the country and valued at £250,000. The retired advertising executive, of Whitney-on-Wye, Hertfordshire, said the car 'has been my best friend and part of my family all my life'. The 1931 classic, which still runs like clockwork, had done 137,000km (85,000 miles) when he bought it and has clocked up 161,000km (100,000 miles) since. Mr Harrison courted his wife Jenny in it during the early 1960s.
