This has been discussed, but most people's driving is Schedule B.
If you are just using it as disposible transportation, don't do anything.
If you are just concerned with keeping the warranty, do the bare minimum. [:I] If you want peace of mind and a bit better resale, do a bit more.
If you are a fanatic about the car and/or maintenance, change the fluids frequently, upgrade when possible and keep it clean!
If you've got ABS, have the brake fluid flushed (including the stuff in the unit), and do the full trans flush too. I'd also check/service the battery and ground connections, rotate the tires, and really look over the mechanical components.
