Summary of the problem:
Diego=Red
Ingrid=Sedan
White then Green
Rachel then 2 then Minivan
SUV then Anton
Yuna = Green
Yellow then Convertible
Rachel then Blue
Sedan=white
Now begin to combine in order:
1. Rachel
2 Blue
3 Minivan
Since IngridSedanWhite is followed by YunaGreen, these do not fit as 1,2 or 3 so they must be 4 and 5
4 IngridSedanWhite
5 YunaGreen
The only place yellow then convertible will fit is in 1 and 2. So:
1. RachelYellow
2 ConvertibleBlue
3 Minivan
4 IngridSedanWhite
5 YunaGreen
The SUV has to be 1 or 5, but Anton is behind it so the SUV must be #1. So:
1. RachelSUVYellow
2 AntonConvertibleBlue
3 Minivan
4 IngridSedanWhite
5 YunaGreen
The only color missing is Red so Diego must be driving the minivan:
1. RachelSUVYellow
2 AntonConvertibleBlue
3 DiegoMinivanRed
4 IngridSedanWhite
5 YunaGreen
This leaves Yuna to be driving the green pickup truck.
