I don't think this kind of survey has been done.
Borrowing the idea from Car & Driver (the older issues), I thought it would be interesting to rate the cars we own on different items.
I figure that (hopefully) the 0-10 scale is most familiar (0 being poor; 10 being excellent).

I own three cars, so I won't rate them all at the same time. And I'm trying to be fair... I didn't give a whole bunch of "10s". If anything, I may be too critical in rating a few of the items.

So if anyone wants to jump in and rate their car(s), go ahead!
Anyway, here are my ratings for one of my cars to start with:
1969 Cadillac Fleetwood Brougham, 4-door 6-passenger sedan.
