@MAY03LT My Father is giving me his Yukon. It has 100614 km on it and has been in heated garages since new. But still driven in the land of ice, snow ... and salt. I'm very grateful but nothing comes without a cost. So I'm thinking given the age, it might be proactive to do the 100,000 mile service from the manual. Now. Something I'd probably do anyway if I had purchased something without knowing the history of it. But ... times are tight everywhere these days and I'm no exception so thought I would ask if you people thought it wise ... or overkill? P.S. MAY03LT. I still have my '96 Z71 at 340,000 kms. on the road thanks to a few of your videos. Many sincere thanks.
