7 or 8 years ago a local appraiser told me of a 71 Nova, with only 25K miles on it.  I told a buddy about it (he's always wanted one) and we went and looked.   It was very plain, manual steering and brakes, rubber floor mat, but did have a radio.   It had a straight 6 with a "Torque Drive" transmission (basically a Powerglide with some parts removed and needed to be shifted manually).   

Same type of thing as this Ventura, elderly lady had it, didn't drive it much, and it was in excellent shape.    It took a little convincing, but my buddy bought it.     He had it a year or so, then parted with it as he had a few other projects going on at the time.    He told me last year that he kicks himself every day for selling it.

While the Ventura won't have the following of a Nova, if they're asking $5500 someone could probably pick it up for $4500, and have a good car.
