If it helps, I had my 1995(M) LS400 converted nearly 3 years ago. Was a bit expensive at £1700.00, but have calculated a saving of between 7-10 pence per mile depending on the type of driving. So you can work it out.
The tank takes 48 litres and is located in the spare wheel cavity. So, you will have to carry one of those repair cans or puncture kits.
In terms of performance, difficult to say really. I think it is down a bit, but if I wanted top performance back, I just flick the switch back to petrol.
1200 plus LPG sites in the UK, haven't really run on petrol now since I had it fitted. Saved myself the price of a case of champagne when we went to France. Tastes better than petrol!
Small point, you cannot use the Channel tunnel, and if you want to use the ferries it must have an auto cut off switch (apparently, but the ferries never ask)
Cannot fault it. Wish I had had it done years ago.

Geoff
