is this car has a timing belt or chain? i need to know if have to change it

That car has a chain which is not a service item, it's only replaced as necessary and is fairly uncommon to go bad. The best advice I can give you and anyone else ever looking to buy a used vehicle is GET IT CHECKED OUT BEFORE YOU BUY IT, and use a quality experienced (with that make of car) mechanic to do the inspection.

Is also very Importatnt the amount of milles that vehicle have an how was maintained . We also check provide vehicle inspection report before you buy it .Have a good purchased .
