Four trips to fix oil leak that was never fixed and had four different reasons for the leaks. Three trips for check engine lights with three different reasons for the light. Final trip determined that we needed a new engine for $12000 new $6000 used or $6500 repaired - invoice stated we declined the repair. Still had problems with the initial repair - Had to get rid of the car - lost over $3600 unnecessarily.
Lesson Learn: seek a 2nd and 3rd opinion from other automotive services especially if you own a Toyota. They should have determined we needed the engine on the first trip.
