Grew up with V8 Fords and Chevrolets. Mostly Impalas,Caprices,Cadillacs and Ford Panthers. The bulk of them were 1 to 2 years old when we bought them. All were excellent vehicles. All were extremely low maintenance. We keep up with maintenance on all vehicles. Now we buy V8 [5.3] Tahoe,Suburban and Yukon. Was very reluctant to go with the Direct Injection engines but so far [between 70-100K miles] just has been regular maintenance. All get decent mileage on plain old 87 regular fuel. Gets the same mileage [around 24-25 MPG] if it is all highway. The same mileage as the 4.6 Panthers we used to own.
