C6 durability questions
Currently have a '91 C4. Am upgrading to a C6 this Fall/Winter. I have several questions about the durability of some of the components of the C6.
1) Is the new 6-speed auto trans as solid as the older 4-speed auto trans? ('05 vs '06)
2) What kind of life span does the selective ride control have before parts need to be replaced?
3) Are there any known or common problems with the Navigation system? (It's a nice feature, but a quality Garmin, etc GPS system would be an acceptable alternative if the factory GM system is poor.)
Thank you for your replys.
Glen
