Film about a younger's brother borrowing a car to show off and got into trouble

My wife has lost hope to find a movie she watched back in 90’s or maybe 00’s though she remembers the plot.

A young guy want to hang out with a girl next door but he’s not cool enough for her. And then his elder and prominent brother hides his car in their parents garage (younger brother is living with parents). So evidently our guy is taking the brother’s car (could be a red cabriolet but not for sure) to take that girl out. And while they are riding they find that there’s a dead body in the car. There’s bad guys, FBI involved. Kind of a comedy, maybe a bit dark.

Mystery Date (1991)?
