The Yaris has a relatively simple lineup, with a single model offered for each body style and transmission. Although air conditioning and keyless entry are included in all models, unless you option up you'll get manual wind-up windows.
Factory options are consolidated to just a couple of main option packages, along with a few standalone options. A Power Package brings power locks, windows, and mirrors, along with remote keyless entry (and upgraded trim in the sedan), while the Sport Package includes front and rear spoilers, side rocker panels, front fog lamps, an amber tachometer, front sport seats, a leather-trimmed steering wheel and shift knob, and an upgraded sound system with XM satellite radio compatibility, an auxiliary input, and iPod connectivity. An all-weather package brings rear heater ducts and an upgraded windshield washer. Fog lamps and cruise control are among the few items offered a la carte.
Toyota also offers an array of accessories, available through dealerships, and while it's a very short list compared to what's offered in Scion vehicles (like the comparably sized xB), the Toyota Racing Development accessories are especially noteworthy. Suspension modifications, a sport exhaust, and 18-inch alloy wheels can all be supported as part of the factory warranty, when purchased at the same time as the vehicle.
