I would be taking delivery of my first Lexus vehicle next week. I thought I will go with GX550 O+ as my first Lexus. Got confirmation that it in port and to be delivered next week. My question is would make sense to but the following from dealer 1) Lexus Warranty Service plan 2) Warranty plan both for 6 years? I am not taking tire/wheel coverage or the dent plan. Appreciate feedback.
