How much driving are you actually doing on each car, how much will you actually save by changing to LPG, and how much will the conversion cost.

I'm doing about I'd say 6-8 k per year total. I think the conversion to be done properly would be about 1500 sterling. (rough estimate, I'd go to the lad that did your man's disco)
So, in that car, I'd do maybe 3k per year (it's been garaged for the winter), but I'd tend to use it more if it were on lpg.

I have as a second car a beautiful low mileage impeccable merc 500sl. It's 1994 Japanese import, so rhd, no rust etc. It's pretty much pristine. Hood works, hard top,etc.
Now my other car is also an impractical enough two-ish seater petrol guzzler.
I've been thinking of selling the merc, as I don't often drive it, and getting a runaround like a nissan leaf.
I can afford the petrol, but it only does about 22 ish mpg, and it irks me slightly for whatever reason, probably Catholic guilt.
One other option however would be to get it lpg converted. I told a pal, who was horrified, and said that that particular engine remains one of the finest ever built, and it would be a barbaric act. He days it's appreciating in value anyway, and I'd be an idiot to molest it.
It is, however, a cool looking car imo, with a good sound system, and lovely to drive with the roof down, and it would seem that lpg might suit my needs. A friend had his disco lpg'd when.it was new, it's now done 200k miles and it's been fantastic for him. I'm also odd enough that the cost of the conversion wouldn't bother me.
Has anyone any thoughts?

if I have got it correct, the conversion entails a fitting on top of the carb and a gas tank, which can fit the spare wheel well or somewhere out of the way. you wouldn't be changing the engine at all.

3000 km at 22 mpg works out about €600 in fuel per year. You'll save about 40% on lpg, so a saving of around €250 per year. So 6 years to break even. And that's not including lpg servicing. Totally not worth it.

Tricky one, but it really depends on your long term vision with the car. If your merc is a pristine, low mileage example and in the long run you would like to hang on to it, with the vision of possibly sell it a good few years down the line and intend to keep it in a pristine shape as possible for the odd drive and weekend jaunt, than no, I would not convert the car to LPG. This would be even more so, if your car is a rare model, for example the 6.0 AMG or something...
Note these SL's will only increase in value along the years, and even though you do not alter the engine or appearance of your car, it will affect the value if it is clear that the car was converted to LPG. It means to a prospective buyer that you made the deliberate choice to start clocking up more miles in it, and even though the changes to body/interior/engine are very minimal, they make the car less pristine.
If you are not overly fussed with getting a premium return back on the car if you ever would sell it many years down the line, and are more interested in enjoying it more now, then I would say, do your maths as in how many miles and in how many years the investment is earned back, and decide wether it makes sense or not. Make sure you have the conversion done by someone who knows what they are doing, and nothing is as bad, as a badly installed LPG system. These fuel injected ECU regulated engines need a specialised engine management system to get the best out of them.

remember LPG is really only suited to long runs and not stop/ start- city driving

So the car will be nearly €2,000 to tax, not to mention other running costs, and you're worried about fuel consumption over a 3,000km average annual usage? If you could magically make the engine halve its fuel consumption to 40mpg you'd be saving a whopping €300 per year.
I'd say sell it & buy the Leaf.
