I've had mine for 6 years now, bought it with 17k on the clock and its now got 140k, never owned a car this long before, love mine. Might have to update before too long but I can't find anything I like as much without spending out quite a bit of cash so might just keep running it for another year or 2.

Watch out for the wheels/tyres on them, the rims rot on the inside edges then the tyres don't seal and leak. This is extremely common, even on nearly new rims, when I bought mine it wasn't even 3 years old and ALL of them were losing pressure. I've literally replaced all of them with brand new ones over the years (which is not cheap) and at the moment all of mine are okay, although last time I had the tyres done I got the tyre bay to file down all the corrosion again on the inside edge of the oldest one. You need to keep checking the pressures all the time, trust me on this, or you WILL have punctures/blowouts. I had 3 on mine, all because of this problem, and I know a lot of other people who it's happened to.

If you're losing pressure in your tyres it won't be faulty valves, it'll be that the tyres aren't sealing properly.
