Selling my car – because I am trying to lose weight

It is a Chrysler Grand Voyager diesel registered in 2005 but only used from 2006. Always garaged and well-maintained. Has been very reliable and a pleasure to drive. But now I try to walk to work as much as I can and prefer to avoid driving. I have been so successful at that that I don’t use it enough now to justify the running costs and so we decided we can do without a car altogether. It has under 107,000 km on the clock and I am asking 33,000 PLN which is a quarter of the new price for a car that still has half its life to go.
