I originally bought the Lexus Platinum Warranty from Lexus when I bought the truck. I paid $4405 for an additional 3 years and/or an additional 50,000 miles for the full warranty (whichever comes first). This takes me out to 7 years and/or 100,000 miles of full warranty. Then shortly after purchasing, a friend of mine referred me to a guy at Midwest Toyota in Kansas that sells the same warranties at a much better price. I bought the exact same warranty from this guy at Midwest Toyota for $2,605. I "returned" the original warranty to Lexus and received an exact $4405 credit on my finance package. I can give you this guy's contact info if you'd like. I've passed his info on to about a dozen people already.
I also bought the Lexus Luxury Care Premium Prepaid Maintenance Plan. I chose to pre-pay maintenance through 75,000 miles and/or 6 years (whichever comes first). I bought this through my Lexus dealership when I bought the truck. I paid $3795 for the maintenance plan. I forecast that the maintenance costs in the Lexus-specified 5,000-mile intervals will cost about $7500-$8000 in 2024 dollars (more in real dollars at the time of payment in future years). So shelling out $3795 now to cover $7500 or more in required maintenance made sense to me.
This is a work truck for my company which I wholly own so the write-off for 2024 should be fantastic. I paid off the loan last month.
