Our car, a truly horrible beast, has been making strange noises from the engine for about a year. In January our mechanic deemed it a fatal problem: it wasn't worth the cost of fixing, and it might run for 2/20/200/2000 miles.
It did about the 2000. Which got us over the Severn Bridge into Wales late on Friday night before we ground to a halt. It was clearly terminal.
So we get put on the back of a lorry and taken back home, a nice weekend away abandoned.
The question is, what to do now. Someone has given us a car they had just replaced. But the fuel economy is not good. So do we refuse it? Do we let them sell it and buy something more economic ourselves or do without a car at all? We actually drive much less than most - neither of us commute to work, and we deliberately use the trains whenever we can. So refusing this thing and buying something more efficient might end up with us using an efficient car a little, and someone else taking the gas-guzzler and using it much more than we would.
Much of the carbon foot-print of vehicles is obviously their production - the energy to actually manufacture it. So by not buying a new car you are avoiding that energy use.
I think the best thing we could do is take the car and never use it. Reduce our car travel to zero. That's never quite going to happen, but we'll do our best. We could convert to LPG, but there's an issue with capital there. Capital we need to save to replace the boiler in the house with a high-efficiency condensing system. All donations accepted ;-)
Any better ideas?
