Much obliged,

Your advice is extremely useful to someone like me, who is totally inexperienced of the US used market scene.
So far I have bought all my preowned cars in Europe, where I've had positive experience buying direct from owners, and never from dealerships. My problem at present is the almost total lack of used Lexus LX vehicles on this side of the Atlantic. I am not able to afford a new one, so my only two options are the Middle East and the USA. Both places are ridden with... lack of trust - in one way or another. Funny enough, I don't trust the gulf state's private sellers, and the US private sellers don'd seem to trust me - coming from an ex-commie (pun intended

) country.
Another of my problems is that I am 72 years old, with a highest technical achievement of changing a light bulb

. Therefore, my goal is to acquire a technically mint vehicle with the prospect of carefree use for at least a couple of years ahead. After considerable efforts on my part, I've managed to convince She Who Must Be Obeyed to splash on a 2013 LX570. Unfortunately, our utmost financial limit is 40 000,- all inclusive sale price, as I have to pay additionally considerable shipping costs and a hefty import tax in my country. It would be great if anyone here on Mud will will be willing to help out in my search for a mint 2013 LX. I've narrowed it down to this particular year/model as prefer as newer a model as I can afford, with as few miles on the ODO as possible. Purely for health reasons I would consider only vehicles with AHC, therefore I'm not interested in LC's, which I can find in Europe anyway.
Thanks in advance
