In Troop Beverly Hills, Shelley Long drives a cream colored Corniche shopping on Rodeo Drive to open the film:

But that doesn't have red interior, and it's just her.

was this the rolls royce
?

I saw it in the mid-90s. All I remember is at the end 2 women were getting into a Rolls Royce on Rodeo Drive with a bunch of shopping. As they're getting in the car, a detective stops them and talks for maybe a few minutes. I can't remember for sure how they made the money they were using. I'm leaning towards either robbing bank(s) or jewelry store(s). Sorry for such little info.
Oh, my husband says that the Rolls Royce was white or cream exterior and red interior and a convertible.
