Dollar - Is there any status with Dollar?

I'm wondering if Dollar has any type of status that earns upgrades and the like.... I've signed up a while back to Dollar Express and earned a few free nights... but is there a way they award frequent renters with upgrades and the like?

I rent from them every 2-3 months for about 3-4 weeks at a time....

Thanks

No; Dollar Express is simply an express renter program. Such is the case with all of the value brands' programs (Thrifty Blue Chip, Alamo QuickSilver, and Budget FastBreak).
