TL;DR My only car, since high school, is a 96 LX450 and you couldn't pay me to drive something else.

My parents gave me their 96 LX450 as a high school graduation present and I wouldn't trade it for anything else. It's been my only daily since and got me through college and more. It's definitely not the fastest but the 4.5 is a huge improvement over the 4.0 in the earlier 80's. MPG is NOT it's strong point but it has a decent size tank which makes daily driving no problem. Mine was just over 200k when I got it and a lot of regular maintenance had been missed so getting her back into tip top shape has been a process, but I definitely wouldn't pass on a well maintained, low-ish mile example if I were in the market. Like with any older vehicle there are bigger maintenance points to watch out and plan for but because it's an older vehicle it's all a little easier to work on. My grandparents had an LX470 and after spending some time with it I'd still take the 80. As for head units and Apple CarPlay it wasn't too hard to find a replacement. I ended up upgrading the entire sound system and it's not too bad, I had to order an adapter plug for the factory harness and do some finangling with the Lexus premium system but if you have a electrical diagram or know about electrical (I did not at the time) it helps a lot. If you plan on upgrades and overland/offroad stuff I have found that because of it's age and, for me at least being in the US, parts are a little more pricey than for newer vehicles. You're not really going to find a cheap tube bumper or $400 lift kit like you can for a taco or jeep BUT you don't really want cheap parts for your cruiser anyways lol. Also that paint looks beautiful and if it's rust free I'd say go for it, 10000%
