in miles.
I will go first.
320,000
My old 92 E200 had 735000 miles on the clock when I retired her, my 07 Laguna had 444415 km on her till some cunt decided to t bone me and send her to the scrapyard.
I was waiting impatiently for her to clock all the 4s 
735000

that wont be beaten.
I can keep my taxi until 2026 but was going to change it next January, most of the time it runes great, was driving non stop yesterday for 7 hours, not a bother on her, same last week.
