Hello Simon,
Many thanks for coming back on this, with some useful additional information.
Not wishing to be critical, but your assumptions are simply that, until you prove it to be fact, and the pre-purchase time is the time to do all your homework - not once you’ve got it.
Assumption:- It’s been a company car - explaining the mileage. It may well have initially been, hence high mileage - but it’s a simple assumption. High mileage = motorway driving - again an assumption. Steve Y on here, does similar mileages in his taxis.
Companies seldom (never?) retain cars for 9 years, so where has it been since it’s assumed company ownership? If they have indeed retained it that long, then it might ( just might) have spent its latter years with them as a pool car - with a high number of careful/careless drivers.
Have you carried out a DVLA Vehicle check on the car? This will tell you when the last V5 was issued - which tells you/ gives a clue into how long the last owner has owned it.
Assumption- Full service history (is the be all and end all). It’s good, but the level of workmanship cannot be guaranteed - it should be, but sometimes isn’t. Positive - it’s a really good starting point.
Engine -…’ is there a high risk of engine failure…?’ Apologies, but you seem to be hanging your hat-of-concern on this. Yes you are right that after 180k motorway (assumption) miles that the engine will still be fine, and you are probably right, but there are many other expensive components which can wear out and be costly to replace. Manual or automatic for example? Manual - clutch? Auto - gearbox oil services?
All of the above is intended to reign you in from a dose of enthusiasm, and allow yourself to carryout all the checks you can before committing.
Having said all that, I’ve had a couple of high mileage cars over too many decades to mention, and quite a few worn out low mileage - back and fore to Tesco cars.
Good luck with the homework.
Kind regards,
Gareth.
p.s. The main dealer ( from whom your full service history print out will be obtained ) oowill probably be able to tell you from the service history when ownership changed.
