Putting aside the (snide) comment that it's a Land Rover and should probably be sold on site, check the section in your car manual on long term storage for some pointers, both before and after storage. Chances are that as the proper things weren't done beforehand, there may be some consequences, particularly with the battery not having a small, constant charge applied to it over time. The oil and filter should be changed a.s.a.p. Other fluids are probably okay, although a coolant flush wouldn't be a bad idea to remove any corrosion that may have occurred. Check for where little critters may have taken up residence under the hood and elsewhere. Tires may have flat spots on them, which may disappear after running in awhile.
