So its been about 70,000 miles since the timing belt was last changed on my car. It is a 2010 Accent GS manual. The service book says to do it at 60,000 or 90,000 miles depending on if driving conditions are normal or severe. I am not sure what constitutes severe driving conditions but I do not push or drive the car hard for the most part. I do though live in New Jersey where it can get crazy driving at times if that counts as severe. But either way, I am for recommendations about what should I do. Can I push it off a little while longer or am I a ticking time bomb? The last person got it done at a Hyundai dealer so I was just going to go back there. I got quoted at around $800 for the entire job (belt, pullies, water pump and coolant, etc.).
