It sounds most likely like The In-Laws (1979) , which has a scene where a car gets driven through a paint booth/car-wash-style setup while the authorities are chasing it, and it ends up with flames on the car.

A couple of other movies people often mix this up with are Gone in 60 Seconds and Shooter , since they also have car-changing or escape scenes involving police pressure.

If you want, I can narrow it down further by the car color, actor, or whether it was a comedy or action movie.
