I mean that the MC platform that the Alphard is based on is not only ancient but decidedly "cheap", unworthy of a premium brand, with low-grade steel used everywhere and low rigidity as a result. The new TNGA platform is much more premium-grade and worthy of use in a premium vehicle, but Toyota is able to keep its costs in line with the old platforms only because of its modular design enabling much better economy of scale. Since the current Alphard is already 4 years into the product cycle, Lexus should instead develop a new TNGA-based MPV which the next-generation Alphard can adopt in 2 years. The Mercedes taxis, as well as many models in the VAG family, are still premium vehicles in my book because of the premium-grade platforms they're based on, despite being equipped with few amenities.
