Thieves have been targeting Land Rovers in Macclesfield.
This month three vehicles were targeted in Adlington, Newton and Pott Shrigley.
The vehicles themselves weren't stolen, but parts were taken from them.
Police are urging people to take basic crime prevention steps.
Sgt Simon Mills said: "We would urge those with Land Rovers to keep their vehicles behind locked farm gates at night. Security lights and CCTV is also advisable to provide a deterrent to would-be thieves.
"Anyone who spots suspicious activity should contact police."
"Those tempted to buy nearly new Land Rover parts at knock down prices should be wary, especially if it's on a ‘no questions asked' basis. Simply refusing to buy the parts will help to reduce demand, and in turn, thefts."
Anyone with information should contact Sgt Simon Mills on 101.
Information can also be given anonymously through Crimestoppers on 0800 555 111.
