This is the complete group of the fastest cars you can buy for under $35,000 — the Ford Mustang Ecoboost, Subaru WRX, VW GTI, Hyundai Elantra N, Mini Cooper S, Mazda3 Turbo, and Toyota GR86. We drag-race them all, with our signature walkback explanation of what happened on the run from 0-to-60 mph and through the 1/4-mile.
