I am aiming to get the car for a reduced price

Says it has about 4months tax, good tyres, spare key, No faults, no major scratches. Couple of small stone chips. No kerbing or other issues. But from the sounds of things 1 service which is Maintanence and air con service carried out by VW ridgeway Newbury.
I guess at 18,000 miles 1 service is correct ?
