They do lap up the miles! I wouldn't be too worried by 136k, mines just rolled over 165k and is still going strong.
They do need a few bits along the way, centre prop bearing, the 'guibo' rubber donut between the box and the prop, lower arm bushes and if you're really unlucky - a turbo!
As a daily, mine is great, I see on average 38mpg with mixed driving and the space in the back is very useful. I've moved house a couple of times over the last few years and you don't realise just how much you can get in the back until you try!
Scrubs up ok too for 13 years old!
