Police in the Charleston area are looking for three luxury vehicles stolen from three dealerships in the past week.
Police say the vehicles had a combined value of more than $200,000.
Despite the cars being equipped with high-end GPS systems, the vehicles have not been found.
Officers told local media outlets that a 2015 Audi A8 L TDI Quattro was taken from a Charleston dealership March 11.
The car, valued at just under $100,000, was parked in front of the showroom.
An employee said a key for the vehicle had been switched with an older key to another Audi, the Charleston Post and Courier reported.
Mount Pleasant officers responded to the theft of a red 2015 Chevy Camaro Z-28 Coupe on March 11. That car, valued at just under $75,000, was parked in a front lot.
A 2011 Mercedes S63 AMG was taken from a Charleston dealer March 14.
No arrests have been made. Police have not determined whether the thefts are related.
