This slow-selling car-type SUV stands pat for 2005. Aztek is based on GM's minivan architecture, but has four swing-open side doors and a combination liftgate/tailgate. It's similar to the Buick Rendezvous, but that model has a longer body with different styling, one-piece liftgate, and seating for up to seven instead of five. Aztek comes only with a 3.4-liter V6, automatic transmission, and either front-wheel drive with optional traction control or GM's Versatrak all-wheel drive. Versatrak lacks low-range gearing and isn't designed for severe off-road use. Antilock 4-wheel disc brakes and front side airbags are included with AWD, available with 2WD. Among package options is the Rally Edition group with unique trim inside and out, lowered ride-height suspension, and 17-inch alloy wheels vs. standard 16s. Also available: rear DVD entertainment, GM OnStar assistance, leather seating, satellite radio, in-dash CD changer, and CD/MP3 player. An optional trailering package allows towing up to 3500 lb.
