 Today my 07 Corolla hit the 100K mile mark.  To date, the overall MPG is 34.08.  At 74K miles the engine component module went out but was covered by Toyota.  At 81K miles, the intake manifold gasket was replaced for $135.  These are the only problems Ive had with the car.  The OE G/Y Integrity tires were worn and replaced at 48K miles.  I replaced them with G/Y Assurance ComfortTred which gives the car a quieter and more stable ride.  There is still plenty of tread after 52K miles.  The brakes are original.  Seating position is good except very little lumbar support.  I use a little pillow.  Im 62 and am comfortable driving 500 mile days.  Its a very good econo box.
