I'm a Avis Preferred member and recently got an email from Avis advising me that I'm only a few (4) days rental away from qualifying for Avis 1st. It also included a coupon code for a free upgrade for my next rental.

I don't normally rent a car for as many days as I did this year and don't see that changing next year. So, is it "worth it" to be to get those extra four days? I can easily justify 3 days in my future travels so I guess I'm really only 1 day away.

Also, if I do make it to Avis 1st, how long does that status last?
