Hey mate no offense, but the Celsior is an imported toyota vehicle, it actualy came out as a Toyota, not a Lexus..and people just put Lexus badges on them. The LS 400 and LS 430 were actual Lexus vehicles, but not the Celsior.
Go n google "celsior pictures" and you will see it comes up as toyota celsior and each pic, the vehicle has toyota badges.
