The Hyundai Accent is not a bad car,
Safety - well it doesnt come with air bags, ESP and stuff.. so just drive safe
Fuel Consumption - it will do nearly 12kmpl with careful driving on an Auto
Spare parts - they are freely available at agents and at other places in delkanda and panchikawatta (Eg - Ajantha Motors)
Yeap it would have pass the 100k mark. and make sure the owner has the service records and everything..
grey areas - as with most of korean cars, its better to check the Timing Belt or confirm with current owner weather the timing belt is changed.. if its not, its advisable to get it check
and a bit of a personal advice, its better to take a mechanic when you inspect the car. and kindly do a search on the auto lanka to get more details.
