* Maintenance: Regular and proper maintenance is crucial. A well-maintained Impala can last much longer than a neglected one. This includes oil changes, tire rotations, fluid checks, and addressing any issues promptly.
* Driving habits: Aggressive driving, frequent short trips, and neglecting to warm up the engine can all shorten the lifespan.
* Climate: Harsh weather conditions (extreme heat or cold) can put extra stress on the vehicle's components.
* Accidents: Significant accidents can cause irreparable damage, shortening the car's life.
* Rust: Depending on where the car is driven, rust can be a major factor affecting longevity.
While some 2006 Impalas might still be running well today, others may have already been scrapped. A reasonable estimate for a *well-maintained* 2006 Impala might be 15-20 years, but this is just a rough guideline. Many factors influence a car's actual lifespan.
