I found a set of sport seats for sale in the local paper, I went to look at them yesterday and they are in very decent shape. passenger side has no tears and the drivers side has 2 tears about 2" each on the side bolster.they are the corduroy/vynil type

My questions are

1. what's a fair price for them

2. How can I tell wich year they came out of, the guy said they came out a 72
