Well, I'm almost in denial - but at 92,000 miles Scarlet had her first CEL yesterday as wifey left the grocery store. Just a P0420 that hasn't immediately come back. While inspecting everything under the hood I noticed low coolant in the overflow and subsequently found evidence of Dexcool residue under the T-stat housing, so she's coming due for some maintenance. I'd hoped to wait 'til 100K but it's close enough - this will be the first "irregular" maintenance I've done so I'm still happy with her track record. Taking 'er to Maine next week, yee ha!
