I find to myself anyway that interior of a car is not overly important. As long as the necessary guages are there, some adequite seating and carpeting exist, thats about all I want. It doesn't have to be in top condition, a rip here a missing part there doesn't bother me. The outside is another matter.
One of the coolest cars I was ever in was a 69 Firebird with enormous power under the hood and looked fabulous outside. Inside was sun faded carpet, torn seats one interior door panel missing with a pair of vise grips to roll the window up and down. When the monster was idlingyou better have everything stowed or it would be on the floor, when she was letting rip the rear view mirrors reflected a 10 on the rictor scale. The buzzzing in the ears from the engine noise took a couple of hours to reside, and the smile on your face during and after the flight would not leave easily.
In fact I guess my feeling is if its too finished You can't play with it
P.S. This is not intended to knck anyone who does like interior perfection, I'm just wondering if i'm a oddddball
