I thought the Silverado had a chrome bumpers, chrome grill, and leather seats?
Yours seems to have been blacked out, and gray cloth seats.
Though I assume they could've been changed over the years...
Or are you using Silverado retroactively as the truck name? I ask 'cause my 1989, short cab/step bed, cloth bench, stick-shift truck, is actually a Scottsdale.
OP: my advice is maintenance. Change the coolant, tranny fluid, t-case, f&r diff oils, p/s, and brake fluid. Check and replace any leaking seals. Then replace the air & fuel filters. Get that thing completely up to date. That way you know how it was treated is its former life. Get a good look at the shocks and brakes while you're at it...
