First time test-driving new cars, tips?

Hi, first post here.I got my Miata a couple of months ago, and since then I've caught a serious case of the driver bug, and just want to drive a ton of sports cars. I'm not planning to get rid of my Miata or buy any other car any time soon, but I would like to test-drive around and try out whatever I can. I'm going drop by the Mazda, Toyota, and Nissan dealerships to test-drive their respective new sports cars. I may be overthinking this, but I'd like to get some tips on getting the most out of my test drive(s), and what to say to the salesmen to get minimum shit.Should I be worried about my appearance? I'm 21, male.Should I take my Miata or borrow my mom's Camry (2016 SE Hybrid)? Would taking the Camry cause a different reaction at the Toyota dealerships?Should I come clean and say I'm basically just test-driving for science, or should I be more vague? What lies do I need to tell? What stories do I need to make up? via /r/cars http://ift.tt/2s5soaP
