Is there anyone who flies the CLS B742?

I ask because I'm interested in late 1970's/1980's air traffic, and CLS offers a wide range of that: ....
1979's PanAm B742
1989's NorthWest B742
United OC, TWA, classic KLM's and so on.

Some people say that the CLS B742s don't offer a precise FMC, but... you can simulate the classic airlines.

Thus, it's worth enough and you might wanna do it without a precise FMC. So I think the CLS B742 is worth a buy. What do you think?

Edit: This has been classic aviation in classic liveries:
