LPG installation

[Tattysnuc]

Hi folks,

Apologies if this has been covered elsewhere, but I had a quick search, and nothing obvious sprung up.

With the fule prices beign so high, I'm seriously considering the cost of an LPG converstion, but I know very little about them

I believe they need a pressurised cannister to be mounted somewhere inside the car....?
How much do they cost to install? Is it a lengthy process? Good experiences/Bad experiences with installations?
Is every car convertible?
If not, why not?
What effect does it have on the MOT test? Do you have to notify DVLA?
How do you fill the LPG tank?
How big are they?
Are they any less efficient in a £/mile ratio - we havea Rover 75 '54 plate, and it guzzles the petrol compared to our old car (peugeot 106) No longer 12 p/mile more like 25p
How do you switch from one fuel source to another, assuming that both remain?

Can someone lend me the wealth of their experience with this as I'm genuinely interested and would like to know more.

Many thanks

Thanks for all the feedback folks - there's certainly a lot in there to research. I was rather hoping it would be a simple case of plug and go, but I'm now having second thoughts. Selling the car is not really an option - we just had to spend a grand on a new clutch, dual mass flywheel, gear selectors etc so I was looking at a way to try and cut the running costs, and this looked like the "lowest hanging fruit." Think I'll give it a miss for now.
