What have you done to your car lately?

Gave the Camry a wash, changed the oil and filter (looked fine for 1300 miles overdue), got the original spare out of the trunk and put in a newer than 1998 tire in there, added some bling and mounted my fire extinguisher in the trunk. Can never be TOO careful.
Oh, and I also trimmed the rubber floor mat where it was getting hung up on the clutch pedal. Been meaning to get around to it.
