It's untrue that JDM Vehicrosses have to be converted to miles when they are imported into the UK (to pass the single vehicle test I assume). Mine isn't and I've seen three others which weren't it's all about preference. My MOT test doc states the odometer reading in kilometers (127KKm). So 135KKm for the LPG VX on Ebay could be correct although a mix of miles and kilometer could also be possible as AA mentioned.
