Did not do the 1K inspection, only the 5K and 10K requirements. I did return to the Dealership prior to 5K for an issue with the roof/gap/seal alignment (Convertible) and to have them look at the drivers door gap aft section lower area (protrudes slightly more than the pax door). Some have reported that the Dealership overfilled the Oil amount, have to admit I don't know if that's the case with mine. All our Lexus's have and continue to only use the Dealership for maintenance. The only difference is for any major body repairs, then it's the local Toyota Dealership.
