They both make sense, but the second one is not quite right. A native speaker would not use 'until' here. The first sentence is fine. It tells us that they couldn't afford to buy a car immediately - they saved for about five years first. First they saved, then they bought the car. The second sentence is understandable, but not natural. The word 'until' means 'they stopped saving when...'. The word 'until' tells us about the point in time when the saving period stopped. The only way that 'until' would work in this context is if you said "He and his older brother saved for about five years until they had enough money to buy the car."

Before and Until >> Their meanings are very similar and sometimes they may even be used interchangeably. BEFORE >> means earlier than UNTIL >> means up to a certain point in time - If you say " they are saved for about 5 years (before) they bought the car ", you are implying that buying the car is the earliest possible event , but they may still saving money after buying the car . - If you say " they are saved for about 5 years (until) they bought the car", you are implying that they will definitely no longer saving money after buying the car. i tried with my knowledge to help . so i hope this helps

sorry for misunderstanding in the first part of the sentence , updated the answer .

Tank you for your help, urusaikidd. I am confused too.

Yes, they both make sense and are interchangeable without any difference in meaning (i.e. the brothers saved their money for about five years, then had enough to buy a car). No offense, but I am simply not understanding why Ahmed is adding "are" in the equation? I hope that this helps you. J.
