Right now I am in the process of assisting my daughter look for a replacement for her 2004 Grand Cherokee. We're looking for a 2014 to 2018. Yesterday, via internet,I made nine inquiries and received a carfax report on each. Seven of them listed previous collision reports or insurance claims. As there is no specific information about these, these seven were quickly and easily discarded. We will now have a look at the remaining two and check them out thoroughly. Carfax saved us a ton of time and effort weeding out the unwanted ones.
Those still might be worth following up on, if the price is reasonable and sellers have records of what work was done. Even if they traded, here the dealer will provide us with the previous owner's name and contact info. I would have done that with the Colorado which prompted me to start this thread, but at the time it was a seller's market plus dealers were really milking the Covid for all it was worth. The 2020 truck I drove down to look at sold while I was on the road.
