Hello, I’m looking for a GMT800 1500 Tahoe or Suburban. I would like to ask you about differences between 2003 pre-facelift and post-facelift models. There is a huge price difference between them and I wonder if it is worth it to pay much more for the 2003+ model year. Was there a traction control system in 2001 Tahoes and Suburbans? Any clues would be helpful for me.

Regards,

MC
