Two shots of Kotch's(Walter Matthau)son and daughter-in-law's 1971 Dodge Coronet Station Wagon. He rides around in it during one segment, so I'd say that's three stars.

A GMC "New Look" bus that his grandson's babysitter takes to the local pool. He follows them there and helps her out, but the bus is only shown for a moment, so it's two stars.


This is the babysitter's boyfriend's car. A late-1960's Pontiac GTO without hideaway headlights. Two stars at least.

Kotch's son's other family car. A 1971 Chevrolet Chevelle Malibu convertible. Two stars.

Kotch talks to his son about the babysitter and her boyfriend's tryst on the son's family couch.

This one's kind of tricky. As his son and tranqued-up wife are taking him off to visit the old folks home, we see other senior citizens riding around on one of these.

I don't have too much proof, but I think it might be a Taylor-Dunn. One star.

Here's another one-star vehicle. A 1971 Ford Custom 500.

I thought it was a Galaxie 500 at first, but the lack of trim made me think otherwise.

More to come later, including a 1949 De Soto that Walter Matthau drives around Palm Springs.
