Pull out the dip stick and put the oil in between your finger and thumb to see if there are any gritter bits in the oil ,when you test drive the car put the car in a full left hand lock to see if the drive shave bearings are knocking and then do the same in a right hand lock.If you are not sure...
I would say no for on a ten year old car , you will have to do very high mileage ,to get you money back ,and i think your car will be then past
it,s sell by date .
I hope this helps you .
