I don't doubt the odometer, if that is how I sounded, ..........I have a 2013 impala sitting in my garage right now with 40,000............I have to put a trickle charger on it, in between wax and dust..........that must have been how your monte got treated for a lot of years๐
I bought my 72 in 73, but it did not set in the garage.........we put 160,000 on it before it got a rest..........I am slowly trying to make it look like yours once again.......if i live long enough........
I like my impala, but it's a lot more fun cruisin in my monte....
