You think you have worries!
As my car is used for private hire ( taxi ) it has to be tested every 6 months.
I purchased my 1.8 vvt in March at 22600 miles and had its first test. This was at 2 years and 9 months old.
Because we can get the vehicle tested up to a month early, it was tested yesterday at 34236 miles, and happily passed again with no advises.
I hope it's going to be as good as my last car; a 52 reg 1.4 Astra G estate. Puchased at 70k, that was used until 150k, ( 3 years ) and passed every test first time, with no mechanical work apart from 2 cambelts and water pumps. I gave it a full service every 10k.
Sold it to one of my daughters, and that passed an MOT today, again with no advises.
