Sequoia is probably the better fit for you as others have mentioned honestly, but the 200 series will make you happy and scratch that itch. Ive had a bunch of Land Cruisers, been in various SUV's, mid and full size trucks - RAM 2500 Cummins etc but there is nothing like a Land Cruiser. Yes there are some cons to both, but if you 'want' a cruiser, get the cruiser - either one will work for your needs. I have a family of 5, and it works just fine in my LX570 and I dont use the rear seats.(in fact removing them soon). In markets in EMEA, the land cruiser is the largest SUV you can get, and some of those markets dont have minivans - families cope just fine with a land cruiser. If you dont use if for offroading and IF you ever want to sell it one day - you'll get better money for it - original, never been off road etc. I'd shop in around the 45k-60k range, you can pick up a decent 200 - the LC or the LX for that price - and you'd get a bit more and a better deal with the LX. Same vehicle, just spec'd different - suspension, front and rear etc. Just dont get one with 21 inch wheels like I did, LMAO.
Good Luck!
