I have the mid-year airbag introduction service manual supplement and it actually calls the air bag a 1988 3/4 option. I found that funny as you always hear of mid-year (1/2) models but never 3/4 models.
The exterior styling of that 1988 convertible is still stunning 25 years later. The interior dash styling looks a bit dated to me but still nice compared to many newer cars, but I guess the interior styling of the 1994 LeBarons I owned grew on me over the original. I still miss my LeBaron convertibles.
