Low milage is very rare in a mk4 now.good luck finidng one. remember though, its not the milage its how its been looked after. i know people with mk4s on 200k+ still going strong and equally iv seen people on here with mk4s that are less than 100k having problems....
I wouldnt worry how many owners its had focus more on service history and condition, plus your 17 i doubt if u buy a 1.4 golf etc you wouldnt plan on keeping it for ages would you ?
