You mean SCL? Also the buses don't terminate at SCL but inside the city at Estacion Alameda or Estacion Santiago.
I personally have taken 6 different bus companies on this route.
The best (for this 7-8 hour trip) are Turbus, Andesmar and CATA.
Tickets can safely be purchased day of or day before at the Mendoza bus station EXCEPT DURING A CHILENO OR ARGENTINO HOLIDAY WEEKEND! Buy days in advance for this situation.
Get seats up front across from the driver's side for thrilling views. The highest peak in SA will be to the north. Take a jacket or sweater for the border crossing and something to snack on but do consume and trash all fresh produce before the border.
