Well, that's just it... car dealers are going to get big checks every day. They're not going to let deposits sit around. They're doing a nightly deposit I'm sure.
Some companies frown on nightly deposits for fear of robbery.
They stagger deposit days around to keep would-be thieves guessing.
I don't know if your Jeep dealer has any such qualms, but it's pretty common practice here.
Heck, even my homeowners' association hangs on to my lousy check and it doesn't clear for 10 days! $120.00, fercryingoutloud! *rolls eyes*
