Ehh I dunno about modern toyota/lexus build quality. It's hit or miss like it seems in the effort to make fun cars toyota cut build quality from their budget, especially the ones made in USA/CAN.
1. Toyota Crown very good lexus like build quality. Toyota land cruiser awful hard plastics.
2. Lexus LX/LC still reign supreme in build quality but the LS seem like an afterthought no effort compared to the build quality of the LS430/460 in the past. Let's not talk about RX/ES/TX built in north america
