Compare, Buy, and Upgrade the Tesla Model 3 and Model Y
The Tesla Model 3 and Model Y are the best-selling EVs in America — and everything on this page comes from actually living with them. Whether you’re still deciding (see how the Model Y stacks up against the Mustang Mach-E, or what a Model 3 really costs versus a Honda Accord), shopping used, or outfitting a car you already own, these guides cover it: honest comparisons, total-cost-of-ownership math, and the accessories that survive real ownership.

Every guide below is written by a real owner, with specs verified against the official Tesla configurator.
