I'm all for being critical of it. I don't think the older LC's were as special as you do. They're just metal and paint. I hate to single out the 100 - but it's probably the least desirable of the LC lineup. Mostly due to the weight, front suspension design, weak front diff, and low power engine. It's by no means a bad vehicle. It's just 25 years old and fits a bit between the LC80 that is probably the GOAT as far as wagons and the LC200. A lot has improved since then. I also think the J150 is a better vehicle regardless of the name. The name is the emperor's clothing here. It doesn't make the metal and paint work better or last longer. It's the product. The LC250 appears to be a big jump up from there. I couldn't care less what they call it.
I am pretty critical of the LC250. There's a dozen things I'd change on it. It should have at least 3 engine options - the Turbo 4, T4 hybrid, and TTv6. It should be offered in a 3 row. And, it should have come with eKDSS optional and double lockers and 35's. I'd also really like to see a panoramic roof panel that comes off. The body is already designed around it structurally. Why not spend the little bit of extra effort to make a two piece removeable top panel? My list of wishes is pretty long. But in general it looks like it's a LC300 rolling chassis adjusted for the body style differences and a pretty decent wagon body on it.
