Tessa: I'm going to buy a new car today! My neighbor works for a car dealership and he said he could get me a good price.
Nick: Are you sure you can trust him?
Tessa: Absolutely! He's definitely on the up and up.
这里的意思是be honest. 对某人诚实，可以说：be on the up and up with somebody.
I bought a used car yesterday, but I don't think the salesperson was on the up and up. He said it was the only car in its color and today I saw a dozen exactly like it!
我昨天买了个二手车，我觉得销售员对我撒谎啦！他说这样颜色的只剩这一辆了，结果今天我看到满大街都是同样的车！
总之，"be on the up and up" 可以解释为"legitimate""honest""respectable" （正大光明的；诚实的）。比如说当有人误解你暗箱操作，而你实际上并没有这么做时，你可以站出来理直气壮地说：
Everything I do is on the up and up. I am totally honest.
我所做是事情都是正大光明的。我没有撒谎。
