Buying used Bilstein 5100s

There is a set of Bilstein 5100s with a 2" lift for sale on Facebook Marketplace in my area. I have a TRD Off-Road, which already has the factory Bilsteins, but they have 122,000 miles on them. Would you advise against buying these used ones? My taco still rides great, but I wouldn't mind a lift and some newer shocks. Any advice from the more experienced people out there? Do these ones appear to be in good enough condition? Thanks in advance.

The add:

 

It's hard for me to tell, is the $200. foe everything? If so, I think it's a pretty good price. 20,000 miles isn't bad if it wasn't all heavy duty off road miles. My Bilsteins have 200,000 miles, and I've replaced one rear shock and the other is leaking now and needs replaced, but the fronts are still going.

 

It was $200 for everything. Unfortunately, we were not able to work out a deal since my truck has been in the shop since a Christmas Eve accident that wasn't my fault, and I don't have a vehicle. The guy wouldn't deliver.
