Positive, No chain or belt to break. Negative, Noisy.
Belt drive is quieter, but can be damaged by stones caught between belt and sprocket.
Timing belt/chain or cam belt/chain
The advantage of having a belt drive is that you don't have to worry about the chain coming off. The disadvantage is that you need to replace a belt every 2 years or so.
No, the timing belt ( or chain on some engines ) drives the cam shaft (s). The serpentine belt drives the alternator, air conditioning, power steering, etc.No, the timing belt ( or chain on some engines ) drives the cam shaft (s).

Advantages of chains over flat belt drive Smoother operation Quieter running No mess left on the rear wheel, like a chain leaves Very low maintance it last longer than belts.
Belt drives can be used when the distance between two shafts(for transmitting power) is large and are relatively cheaper than gear drives.
its a chain that drives it no a belt
I personally think belt drives are better than chain drives because belts won't squeak after a few years. I'm still looking for just a belt that I attach to my pedal so it'll be cheaper.
It does not have a timing belt. It has a chain that drives the camshaft. OR do you mean the serpentine belt on the outside of the engine that drives the alternator, A/C, water pump?
Yes, they did - although they were very unreliable! They wore out quickly, often broke and were damaged in rain! Today we have chain drives, but belt drives are still available for a cheap sum of money.
it has both a timing chain that drives the intermediate shaft and a timing belt that runs the cams
