So sorry to hear of the loss. I would be gutted, its like losing a family pet.
I had my car stolen a few years back - found it two streets down as it was on the absolute red on the diesel - I found it walking the dog! No damage, but I have always kept my Landy now on absolute zero fuel for what i need. Thieves may have just taken it to "get home" - means they cant get back to L'pool or Manchester without fuel (I live in Chorley, Lancs which is 20- 30 mins from both and both motorways are 5 mins from my house. Thefts, car and house, are just about the only thing we suffer from round here and most is cross border (i work in Community Safety). My advice, the best forms of anti theft is keep your fuel low (if they have to refuel they can get picked up on CCTV, or ditch and find something else, take it out of diff (if old like mine), hard to get mine in when still - even for me, disconnect battery. If going on holiday remove a wheel/put on axle stands - they dont like to chance a broken Landy when they can go for a nice "running" one.
Hope your new addition to family is a loving replacement.
Al.
