My 05 Impala is a joy to drive. The 3800 series engine responds effectively and without hesitation. The Goodyear tires are terrible. I will purchase Michelins next time. The interior is very quiet with no rattles. It handles extremely well considering the size of the car. I have had 5 adults in the car with no complaints about leg room or hip room. The interior is spacious and very well laid out.
The seats are very comfortable and I really enjoy the heat option. The Driver Information Center is very accurate and helpful.
Do away with the Goodyear tires. Add an aftermarket air filter for better performance.
