"Oh, I'll drive." For one thing, Clint rather enjoyed 'borrowing' Tony's cars. The man had one for every day of the month, and that wasn't including the collectors that Clint was literally dying to see. For another, he wasn't in the mood to direct Steve through the traffic in New York and through the back entrance to NY HQ's offices.
The Maserati might not be a great choice, but Clint wasn't known for his good choices. With the pair of them on their way, Clint just nodded to the dash where Steve's traditionally put together file was sitting nicely.
"So, give me the laymens on what you already know so we're not wasting time in there looking for the stuff." And Clint wasn't really wanting to go through old news himself.
