That really isn't an "older" car at all, neither due to age nor mileage.
You really shouldn't be expecting anything more than services to schedule and consumables, such as tyres, brake pads, etc.
Cars currently last an average of 13 years.
My car is 15 years old this Summer and the only "major" cost above and beyond servicing, tyres, spark plugs, brake pads, etc. is the timing belt which was replaced as per service schedule.
A previous car hit 200,000 miles and was still on it's original clutch, gearbox, exhaust, etc.
I really don't think you need to worry. Have it serviced to schedule, drive sensibly (not banging up/down kerbs, etc), and I'm sure you'll be fine for another couple of years easily!
