1990 Chevrolet Suburban Silverado

1990 Chevy Suburban. I purchased it in May from the original owner who had it the last 25 years. Runs and drives excellent. Engine and transmission are very strong. No leaks.
I replaced a couple sensors and the driveshaft center bearing.
Power steering, utomatic transmission, uel injection, ower windows and door locks. Rear heat, /C. Tow package with 5 pin for larger trailers. I have an adapter to a flat 4 for smaller trailers.
Cruise control. Stereo has been updated to CD player with bluetooth, handsfree, phone/android compatible, nd new rear speakers.
Last time i checked the mileage it came in at 14mpg.
I'm downsizing so it's gotta go.
