(Around 34 minutes) Leonard puts on a waistcoat just before Gilligan leaves but immediately afterwards the waistcoat is buttoned up.
During the Race into town in that Big Beautiful Duesenberg, at 11:35 we see the odometer read 00102 miles and the trip odometer read 039. Then at 11:45 the trip odometer reads 044 and again at 12:00 it reads 043. The mileage on the trip goes backwards and the mileage stays the same at 00102 on the odometer.
If that Duesenberg is still alive today it's worth millions.
