Is it worth it to replace full front suspension, front brakes on this 20yr car?

What is your question?

Have 268K+ miles on this car, bought new, almost 20yrs old. Told it needs new front suspension, engine block mounts, new front brakes, plus some small basic maintenance. At this point, have I driven her into the ground? Quoted about $4600/$4800 for repair and they are working with me for that price.
