Didn't realise that the abbreviation of Japanese was seen as offensive. Good to know and thanks.
Funny you mention the 50k figure. In the UK, it is still a mental barrier of 100k miles. Most people consider over 100k to be high mileage and the car on its last legs. Honestly, if a car has been serviced and driven with care, the mileage is just a number. I've driven several of cars with +250,000 miles and they still work just fine. Indeed I remember driving a Renault 21 1.7 petrol with 260k, and it was still a delight to drive.
The highest mileage motors I've personaly owned are my Mk1 Octi that I took to 160k miles, and my Ford Transit that I sold at 183k miles. Both motors were still in fine fettle. Our Jazz with just 96k, still feels fresh and up for the next 100k !!
