Best Gmc Denali Years

The 2009 Denali benefits from significant improvements to the platform and shows fewer complaints. The 2007-2009 GMT900 platform Denalis are more reliable than earlier GMT800 versions. The 6.2L V8 in these years proved more durable than earlier engines. A late-GMT900 generation Denali offers the best combination of features and reliability.
