Although 122,000 miles may be relatively high for a Porsche Macan, as it is now ten years old this suggests an annual mileage of 12,000 which is the average for cars in general. When looking at a performance vehicle such as this the history is everything - we would be looking for extensive maintenance records and receipts for all work carried out, particularly as maintenance on a car like this can be expensive so owners may look to cut corners. The fact that it is significantly cheaper than other examples may be due to the higher mileage, but we would treat this with some caution - you may wish to pay for an independent vehicle inspection for additional peace of mind.
