I’d say repair. In today’s used market, $3,000 will probably get you less than what you have now. (I exclude direct purchases from friends, friends of family, etc. from this.) They are correct, in a perfect world you would replace both sides at 199K miles. You have to decide whether your world is perfect or whether to just fix what is actually damaged.
Does that $2,000 quote include body work or just mechanical? That needs to be factored in.
Are you at all handy or do you have someone who could do the suspension work if you provided parts?
If you do repair, also factor in the cost of an alignment. Mandatory form what you are saying about what needs replacing.
