This would appear to be from April '91.
Only a couple of the photos from this night of shooting are dated - 4/91. At least I'm assuming they're all from the same night. They must be, since they're all in the photo album in the same place. But I got the car just before Thanksgiving, and I thought it was a year-end clearance deal, which would have meant I got it in 11/91 (it was a '90). Apparently I'm misremembering that fact. So I got the car in November 1990.
