Unfortunately the LX and LC bring out the laziness in mechanics. It's pretty damn easy to do an oil change on the high volume camry or ES/RX. When they get a LX/LC it's actually a chore for them. Removing skid plates/etc. My lexus dealer didn't grease the drive shafts. When i had my LC i would have sworn on anything they didn't change the filter, rather did a drain and fill. I now do my own 100% of the time. If i didn't i'd mark the drain plugs and filters and take a pic before service to verify anything was done. Tire pressure is my short fuse. I was really tired of jumping in a car that had just been serviced and the pressures being all over the place with zero rhyme or reason.
