Like Steve said, timing chains (there are 4) are a consumable between 150-220,000km - the car your looking at will have had them done & could be needing them done again in the next 50,000km or so.
That is not what Steve said, and as far as I know, Suzuki does not consider the timing chains as a consumable item, check your owner's manual for the service schedule, you won't see anything in there for them - you'll see one for the timing belt on the G16 engined GVs, but nothing for the chains on the J20 & H25 engined versions.
Suzuki considers the chains as good for the life of the engine, and with proper maintenance they are.
What I believe Steve is alluding to, is if the chains are worn, or the hydraulic tensioner passages clogged, both of which can and will happen if maintenance has been "spotty", they will rattle, and that rattle shows up clearly on a cold start.
The wrong grade of oil (too thick) or the wrong oil filter (no drain back valve) can cause a delay in oil pressure reaching the tensioners, and this allows the chains to run loose and rattle - any timing chain noise lasting more than 1~2 seconds on a cold start is a bad sign, 15 seconds or more, walk away.
