Alternative fuel update

Here's an update to my incoherent ramblings on whether or not I should get my car converted to run on the cheaper LPG fuel. I went to see the Vauxhall dealer where I bought my car to ask about LPG models. I was told they were rarer than hen's teeth, one guy had worked there for three and a half years and only seen one dual fuel model in that time. Vauxhall haven't even released prices for the new shape dual fuel Astra yet, apparently they only make them to order and it can take up to 12 months. If I was concerned about saving money on fuel the guy I spoke to would be more than happy to sell me a diesel car though. Somehow I get the impression I've been a little fobbed off there.

The quote to have my car converted arrived this morning. £1350 including VAT, which is a little less than I thought. However, converting a car to run on LPG doesn't mean you can ditch the petrol completely, as it needs to run on petrol until the engine warms up (apparently) and then it'll switch to LPG. So the figures the spreadsheet gave me are at the absolute top level of optimism. It'll still take two years for a conversion to pay for itself. Also I've heard rumours that the current low level of taxation on LPG fuel won't remain low for ever (but that's only a rumour!)

I'm currently thinking the best option would be to just not put my foot down as much.... so if you get stuck behind a silver Astra on the motorway doing a steady 56mph, that'll be me, sorry.
