I think its all pot luck to be honest!
You could go to VX tomorrow and by two brand new Insignia's, treat them both the same (ie If one car goes out, the other does too!). And its only going to be a matter of time before something goes wrong, and I would put money on the same fault not happening on the other car at the same time (if at all). (Not including common faults, or serviceable items)
I'm not a fan of low mileage cars, unless you know the car (ie friends / family member etc). The other fears of low mileage cars are old granny owners, who have owned it since new who can’t drive properly. My grans fiesta for example is M reg and done 35k miles (ok, its scrap almost because of rust), its only been out of York twice, and that was when my dad borrowed it! So basically its done 35k CITY miles.
The other day my dad went to tesco with my gran (she had been in hospital) to help her restock her kitchen. My dad drove her car, and she said to him when he got on the ring road 'Oh, your in 5th gear!'. Dad replied 'Yes why?', gran says 'I don’t think I’ve ever used 5th gear in all the time I’ve had it! I rarely use 4th too!!!!'
