With the LC4 and LC5 specs, those are UK only. In Australia they are GXL and things like that, so I suspect that in Germany they will be local spec levels - basically don't worry what the guys are saying about "if it's that level, it should have parking sensors" as that is very local market specific.
With the XC90, as the others have said the gearbox is a weakspot in the T6 and 3.2 petrols, but the D5 is fine in that regard. HOWEVER, they changed the Haldex system in about 2006 (I can't remember exactly) in all the P2x cars (so the S60, S80, V70, XC70 and XC90) so if you're going down that route make sure you get one post change.
Hope that helps, I've got feet in both camps (I drive a Toyota 4Runner and used to have a Land Cruiser, and my parents in the UK have had Volvo's for the last 40 years or so...)
as above, LC3/4/5 is a UK model designation, it will differ dependant on country of sale. The model with air suspension on the rear will probably be the highest spec available ............
Good advice above on the XC90 also, many of the earlier ones have transmission problems which results in no rear drive. Many people choose to leave it that way rather than repair.
I have a '07 LC3 (3ltr diesel) and a '10 XC90 D5. Since new the landcruiser has had regular services (by myself), injector seals changed under warrenty, 1 set of front pads, 3 sets of tyres, a few rear bulbs and a set or two of wipers.
In two years of XC90 ownership (wifes car) it has had regular services, 4no wheel bearings, tyres, a fair bit of fiddling with the rear parking brake, fault codes that need resetting and a few other bits.
Relability and maintenance costs wise its no contest (albeit the volvo isint actually bad at all).
As a family car that doesnt need to tow heavy loads or go offroad too much the volvo wins, its an extremely well thought car in terms of use of space, its deceptive how much room it has inside. Nothing comes close (bar the Q7) to the size of the boot when all 7 seats are in use, that is the primary reason we have it. Its a more refined piece of kit but it is a different machine to the LC, horses for courses ! Both of ours seem to average ~28mpg.
I'll buy another LC in the morning (if I had the money), the missus would buy another volvo at the same time.
Statistically, Voyagers are possibly the worse thing imaginable for relability, I dont rate disco's much better.
