There are few retail experiences worse than buying a car. Before setting foot in a dealership, I spend weeks researching makes and models, printing out price sheets and psyching myself up like I’m headed into an MMA bout.“What if he tries to sell me the extended warranty? I’ll say no! Rustproof undercoating? No way! That lease looks like a pretty good opti… NO!”Despite constant promises of zero haggling and low-pressure sales, I always leave a dealership with a pronounced limp and wondering where my watch went.
