2003 GMC Sonoma 2dr Regular Cab SL Rwd SB (2.2L 4cyl 5M)


If I had read the owners manual before
buying I would not own this GMC. The
maintenance schedule is the one I
maintained on l950 vintage vehicles.
Unbelievable. The gas milage of 19-25
was more like 13.5 in the summer (4cyl.
I bought the vehicle for handicapped
passenger comfort and discovered the
floor is uneven on the passanger side.
There is no storage space under the
seats and hardly can get anything
behind the seat.

Best Features

Bought the vehicle based on looks and blind faith in GMC reputation.

Worst Features

Improve maintenance schedule. Eliminate fittings that need to be greased every 3000 miles. Flatten the passenger side floor. Make some storage room in standard size p/u.
