The Silverado is very well made: strong structure and refined, efficient V8 engine.
I was concerned about trading my Toyota which served me well, but the Silverado does some things better. First off, the price was MUCH better!
Even though the Silverado is heavier and stronger overall, its gas mileage is best in its category. Seems that the push-rod V8 uses fuel more efficiently. The engine is well proven.
Ride is smooth. Seats are VERY comfortable. The interior is rather spartan, but I rather like the simple appearance and easy of keeping it clean. I did not buy a truck to be a luxury car.
Handling is quite good and the comfort level is very high overall. The level of quietness is surprising!
Transmission shifts smoothly and smartly. Mechanicals work well. Others I know have gone well over 100k miles with very little problems, even some friends who are not known for taking good care of their vehicles.
All things considered, the Silverado appears to be a very good value. Possibly that is why there are so many on the road.
