How many motor mounts go on a 2007 Suzuki Grand Vitara 4WD?

For any parts, I'd consult the local servicing dealership (if you can find one) and a local aftermarket parts store. You can do a web search online also. As far as "cheap" - there probably are not many options regardless of price for parts for this vehicle. There were not that many on the road in the first place, and the vehicle is 12 years old. Good luck.
