A good illustration of “don't judge a book by its cover“ might be the Pontiac 6000. First appearing in 1982 to take over from the Grand Am in the mid-size sedan market, the 6000 was not flashy by any stretch of the imagination. Squared off and bland, it looked like a respectable family car or the car your grandmother only drove once a week to the grocery store.

Once inside the 6000, however, reluctant owners were pleasantly surprised and grew into loyal fans. The 6000 made Car and Driver's Ten Best list for three years and always rated highly among customers. Starting out as a sedan and coupe, it added a wagon later, and all models were known for their roomy interiors and large trunks. The engine performance was sturdy and reliable, rarely letting drivers down, and with the V6, the 6000 had incredible pickup and enjoyable cruising speed on the highway.

Realizing its potential, Pontiac released a sportier model, the STE, which had a high-output version of the regular engine and sports-tuned suspension and performance attributes. This, along with the car's affordability, low repair record, good fuel economy, and inexpensive aftermarket parts, made it a great package for first time buyers wanting both practicality, economy, and performance. Though most drivers bemoaned its ugly exterior, they gave high praises to the driving experience.

A brief all-wheel drive version was offered towards the end of the 6000's life, as was a 3.1 V6 which supposedly was the first of these in a production vehicle. The Pontiac 6000 lived for 11 years, being replaced in 1992 by the Grand Prix, but most original owners say their cars are still going strong.
