Welcome along.
Good choice of car.
LPG, I've been running cars with LPG for about 15yrs now, everything from a 1.4 Citroen to one of my 280bhp a Subarus. Can't fault LPG conversions and just can't see why it never took off over here like it has elsewhere in the world. Everyone moans about the cost of fuel but are sceptical when a viable alternative comes along.
Depending on make of the conversion, you do lose a little performance on gas, usually 5-10%. However, nothing beats the smile factor at the filling station.
I always carry a space saver spare, just loose in the boot and if travelling a good distance, like abroad, for example, I take a full size spare.
