All valid points. But as said, I'm gonna stick to my guns. I'll put it up for £3500 and if it doesn't sell, I shall bring it down in price over time. I'm in no hurry to sell, so I'll happily see what happens over the coming months. However, most of the downsides you've mentioned are incorrect and somewhat over exaggerated. We now have 6 LPG vehicles of different sizes and over the 10 years we've owned them I've learnt a few things that I'll share with you. Firstly being that LPG is a gas, it's dry stuff to run on. We've found that some inlet valves would stick open (especially cylinder 8 for some reason) due to the lesser (or nill) lubrication that LPG has. In solving this I've found it best to switch back to petrol in the last mile or so of driving so everything if left 'wet' as it were. Without doing this, seals start to perish and when the block has to come apart bills get big. Your point about MPG is a valid one. Anything from 5-10% less MPG is expected. Personally on my Lupo I've only found it to be 6.3%. But when you look at the big picture of your total saving, it isn't really anything to write home about. Performance is a minimal issue, when the system is installed the LPG fuel management system can be 'remapped'. To give a higher power output to exceed or match the standard performance. Without tweaking it (like my mother's Lupo) you can honestly not notice a difference. In the old systems (5-10 years ago) I'll admit there was a noticeable power drop. But no more is this the case. Reliability issues. I can only really speak for our V8 Defender on that one, it's conversion was 11 years ago and apart from it's yearly tunes ups. We've never had a single problem with it. Mine and my mothers Lupo have given us nothing but trouble free miles. And I've never noticed any of our vehicles drinking excess oil, and I personally service every one. Availability again is a downside, but the there are mobile apps, internet maps and sat nav add ons available to find your nearest filling station. Generally speaking, I've never been on a drive longer than 30 minutes without spotting one by eye. Obviously if you don't live near one, then yes there isn't much point using LPG. The LPG tank is generally located in the spare wheel well. So it makes no difference to the boot capacity. Mine being the exception due to the exhaust configuration making it awkward to fit the system practically without loosing what was already a poor excuse for a boot. Other 4x4 often have the tanks bolted to the under carriage providing there is adequate space. Furthermore, upon start up, an LPG vehicle will run on petrol for anything from 1-3 minutes (depending on it's ECU set up) This allows the vaporiser to warm with the engine temperature. Therefore it changes seamlessly from petrol to LPG and continues running as such. Insurance wasn't a problem for me personally. It made no change to my premium. However I am aware some insurance companies do increase the premium due to it being classed as a modification. But not all. I hope what I've said has been insightful and maybe given you a first hand perspective on the matter Cheers, Tom
