Sorry, what i wasn't clear... I purchased it with 25,000 miles on it, it's still covered by the Lexus and the warranty i purchased... In my Lexus warranty, Lexus recommend" that you take the car in for a service every 5,000 miles... I am definitely going to take it in at 30,000 miles just to have the Lexus techs look at it. But after that I was wondering how many people adhere to the 5,000 miles service... or is that overkill?
If you look at what is actually -done- at those 5k services the vast majority are just oil changes and "inspections" where they don't actually -do- anything. Won't stop the dealer from charing a bunch of $ for it though

There's some additional services at some intervals that you're still much better/cheaper doing yourself like the air or cabin filter changes... and then a couple of services that are probabably worth hitting the dealer for.
By and large my suggstion is to change my oil at intervals that make sense for the oil being used (ie 5k for normal dinosaur oil, 7.5-10k for something like mobil 1, and once a year regardless for something like amsoil) and get that done however it can be done properly for the least money- which will pretty much never be the dealership.
Do the filter changes yourself.
Document that you're doing things on a "regular" basis otherwise in case there's every a warranty question.
Hit the dealership for the couple of major services it makes sense to do so.
