I am considering selling my '54 plate Jaguar X-Type saloon early next year.  It runs beautifully and looks beautiful but I find that I drive only a bit over a thousand miles a year now (!).  Before I bought it the Jag was converted to run on LPG so it has a big gas tank in the boot. It was a proper conversation and the car is on the official LPG register. LPG costs about £0.75 per litre at the moment which is a bit better than £1.322 per litre for the cheapest supermarket petrol.  I always run the car on Shell V-Power petrol because it keeps the engine cleaner and running sweeter.

Currently when I switch over to LPG the car quickly stalls - I believe that this is a minor fault which could be sorted by the right LPG mechanic.  The Jag has done under 85,000 miles - I have owned it from 2017 at which time it had done about 77,000 miles - so this is eight thousand miles over four years.  What would members of this group suggest - should I get the LPG fixed to get the best price? And if so where should I go?  I am based in London.

I have since found an LPG engineering firm in London which can do the work I require.  I plan to get this work done in January/February 2022 and then sell the car, probably via this forum in the early Spring of 2022.
