I am 82 and my driving licence has been extended for three years. My Honda Jazz SE manual is nearly 8 years old and although it’s done only 38,000 mileage and has been trouble-free, I expect it’s only a question of time before it breaks down. I am absolutely dreading this, particularly if it should occur during my frequent 26 mile return journeys late at night, including an unlit section of a former motorway (now A414). To reduce the chance of this happing I am wondering whether to ask my garage to replace any parts likely to fail suddenly. Would this be practicable and financially viable? For peace of mind, I suppose the alternative is to trade-in for a more up to date version.
