The guy drives a ten-year old Volvo! It's brilliant!
|― Hank Schrader|
The 1998 Volvo V70 was Gus's car.
Better Call Saul
Gus's car represented how he was able to hide in plain sight. Such a modest and unassuming vehicle would not attract attention or arouse suspicion for his true great wealth. This is similar to how Walter owned a 2004 Pontiac Aztek. The vehicle made a number of significant appearances in the show, such as when Walt was told by Hank to put a GPS tracker on it (""), or when Walt attempted to car bomb Gus ("").
