I'll add another...
Fit your own LPG / CNG conversion:
Broadly because to get to the galactic miles these cars do, takes a heap of fuel, petrol versions could do with a gas conversion. But with BIG caveats, by their very nature, many conversions get bodged in, thus LPG gets a bad rap. Volvo's own factory-fit LPG/CNG cars need an eye on them. The poor install issue is not LPG's fault, but listen to the naysayers, and you'd think so.
Yet done right, and I DO mean done right, gassing a car works. For the savings involved, it's worth grasping, how to apply it, and why. A poor install will be a nightmare. If you're capable of keeping one of these cars on the road, you're capable of fitting a gas kit - and doing it well. If you're careful it'll cost you £3-400 (£550 at most) in parts, and pay-back in months. Depending on your miles, it probably isn't as viable to have a pro fit for you, pay-back will be 3-4 times longer.
