The car has done a fraction over 110,000 miles.
Vw quotes that their engine with the proper maintenance and oil done by the book should last 1350000 miles without needing an overhaul. I have seen many 100 k vag engines where the crosshatching was still visible onto the cylinders walls. Just buy the best you could afford and change the filter every single time. 5000 miles oil interval for fully syntetic oil is waay too early i wouldnot change before 7500 as the protective additives in the oil does not get activated before about 3500-4500 miles so you trowing money on the window.
