Just an update. Went to the local MB dealer to test drive either a minimally optioned '21 with just 3900 miles (polar/beige) or a highly optioned '22 with 20K miles (dia white/beige, AMG, night, DAP, lighting, pano etc). The 22 was just sold as we got there and I was ok with the '21 (the low miles/condition is superb) but my wife has decided that the AMG appearance package is a must. So the salesman brought out a "new" highly optioned '23 GLE (polar/black) for us to drive. Well its not "new" in that it has 9600 miles but has never been registered (MB exec car they bought from MB) which confuses the system since it shows up as new on the MBUSA website vice CPO. anyway I drove it. On the highway, around town it was very nice/comfortable. The tech is light-years ahead of our GL. Getting on to the highway you instantly knew it was a 4 banger. A far cry from the acceleration felt in our 2013 GL450. But I think I could get used to it (or at least my wife would since it would be her daily driver). The dealer was asking $71,800 which is MSRP. He stated that the warranty would run to 1/11/28 with unlimited miles (so basically 3 yrs plus CPO). I went home and sent an email asking about the price, basically why would I pay MSRP for a car with 9600 miles? Why not buy a new '24 then? A quick search showed a number of similar '23s with same miles going for about $67K. Salesman got back to me that the GM would knock off $800 and give me $7K for trade-in ('13 GL450, 94K miles, bought as CPO from them and faithfully serviced). I thought the trade-in was a little low (I est $9K) but understand that it would go to auction and they need price protection. But $800 off for 9600 miles!! I thanked him for his time and wished them Happy Holidays!
