Tab Spangler's Volvo

Tab Spangler's Volvo is a white station wagon which he uses to transport clients to and from the Serenity Ranch fat camp.

History
When Bart was doing poorly with the Serenity Ranch treatment program, Spangler used the Volvo to drive him to Springfield to see what his family was going through to afford the fat camp treatment. Confronted with the true cost of his addiction, Bart was cured and needed no further treatment. However, Bart's quick cure left the Simpsons with three weeks of non-refundable weight reduction treatment to use. After a brief discussion, Homer was chosen to receive the treatment, and Spangler drove Homer in the Volvo from Springfield to Serenity Ranch.

It isn't known for certain whether the Volvo is Spangler's personal vehicle or it belongs to Serenity Ranch. However, since Spangler is the only known employee, there may actually be very little distinction between his property and the ranch's.

Behind the Laughter

 * Spangler's Volvo wasn't involved in transporting Bart to Serenity Ranch. For that trip, the Simpsons made their own arrangements, hiring professionally trained child-snatchers to take Bart to the fat camp.
