| I had my Mini One Convertble converted to LPG 3 months ago. I didnt want to lose any boot space , so I have a "spare wheel" type tank UNDER the boot floor on the passenger side where the space saver wheel would go. This was a tight fit even with the smallest 38 litre tank available, but I still get 230 miles between refills. The bottom of the tank is visible below the line of the back bumper, but to date has not been an issue with kerbs etc. The main benefit is the equivalent of 75mpg on my 100 mile daily commute, although you need to investigate the location of your nearest LPG stations. I have detected no loss of performance or reliability issues over the last 10k miles, and I would not hesitate to recommend the conversion to anyone - the pay back is after aprox 30k miles vs diesel payback usually around 80k. |
