Hello! I suppose the best way is to call a mechanic but it will cost a lot. You can also look for some online consultation services, maybe you can use FaceTime or whatever while checking the car. Youtube will also help you! Btw, do not forget to change the locks after you buy it. I recommend this to everyone after my Β«new carΒ» was stolen the next day after I bought it. You can visit the securelocks.net website, for me, they are the best service and I like their low prices and professional staff.
