It cheap insurance to do the timing belt on any used import car over 100k miles to me. If they dont have proof of it being done i will just do it anyway. It cost me like 125$ in oem honda parts to do it on my civic. Should not be a deal breaker its just a maintance item. And with your buying a 2k car you cant expect people to spend the big money a shop will charge to sell a 2k car. Just like wanting new tires on a new car is it nice to have yes, But would you spend 400$ on tires just to sell a 2000 dollar car?
