In the parking lot of a car dealership in Schwäbisch Gmünd, five cars were on fire late on Saturday evening.
The glow of the burning cars standing next to each other was clearly visible from a distance.
The property damage was estimated by the police at around 60,000 euros.
As of early Sunday morning, there was still no evidence of the cause.
Schwäbisch Gmünd - The police couldn't rule out arson any more than a technical defect.
