The guy in the video is claiming that there are only several IS500 models throughout the entire Europe. If there is only one in the entire Ukraine, there are probably none in the rest of Eastern Europe, and probably 2-3 in Russia - yet S classes, M and AMG cars are selling like hotcakes. This is entirely Lexus fault for not advancing their brand in Europe, and it is a shame. Even before the war, with the limited supply the LX sold for more than the Cullinan in Ukraine/Russia, but aside the LX/GX other Lexus models are generally looked down upon and dismissed as being lowly Toyotas, and often deservingly so, but the IS500 is truly a hidden gem.
The Ukrainian reviewerer is very knowledgeable on Lexus, and he was critical of the IS500 as its not a direct successor to the IS-F, but he absolutely loved it and made a point that this is that last great Lexus with a powerful NA V8. The title of the video is misleading, from what I understood they only paid around $120k for the IS500, but said if it was to be locked in a garage for 10 years it would be worth $400k as a collectors car.
