We're not in NY, but do service many CS Coupes along with other German specialty cars in the NY NJ area. We offer enclosed pick up and delivery of your CS Coupe if you like.
We have rebuilt Getrag 265 5 speeds on the shelf and a very good Getrag 4 speed ready for installation.
There are numerous E9 Coupe.com members here that I'm ceratin would speak to the quality of our work.
Thank you,
