The CADR was a research prototype of a University research lab for a new type of computer, with Lisp hackers developing an early OS and a few research applications.
Of the Apple Lisa roughly 80,000 machines for $10,000 per machine were sold. The CADR would have cost around 8 times more and only 200 had been built. Nothing which had reached the level of a product which one would like to ship to a customer.
"The LM-2 was a popular AI (Artificial Intelligence) machine when it was introduced in 1981. It had a 32-bit CPU with a 12K writable control store, 1MB of main memory and an 80MB hard disk. It also came with a bit-mapped display, mouse, and LISP programming environment. Symbolics introduced the Symbolics LM-2 in 1981. The LM-2 was basically an M.I.T. CADR, repackaged for higher reliability and easier servicing. Symbolics made numerous improvements to the system software and offered options such as Fortran-77, color graphics hardware, and the LGP-1 laser graphics printer.

Yes, they sold slightly improved versions in very low volumes (~ 100 LM-2 were sold by Symbolics, see above), until they had a machine that was a bit more designed to be a commercial product - machines which were still very fragile -> the Symbolics 3600 and the LMI LAMBDA.
