My car is 11 years old and has 120,000 miles on the clock. It has a 1.2L counterbalanced short-stroke tri-cylinder VW engine developed by Ricardo's in Shoreham.
No sign that it is going to fail any time soon. I'm sure that it will easily last another 120,000 miles, or another 11 years easily if I take good care of it.
I'm not sure where you would hear such rumours...
