Sounds to be like bad rings....but 3 quarts in 2 days is just knutty. Are you sure there is no oil puddles underneath the car? I would deffinately get an egine compression test before you do anything. The testers are about $20-30 and it only takes about 10 minutes to do. If you don't know how or don't want to do it yourself, take it to QPR or Elite and i am sure they will do it for a few bucks. Sorry to hear of your bad luck, nice looking car at least.
