Hey, I'm glad you're not hurt too badly. But for the car, it shouldn't be damaged much, if any. I mean, only one corner of the car was jacked up, right? If you want to do any work that takes longer than 5 minutes, you should get jack stands or some ramps. Those spare tire changing jacks are meant for temporary use.
Oh, by the way, did you get my last message to you? I WANT THOSE CAR COVER PAPERS! SEND IT VIA FIRST CLASS IF YOU HAVE TO. I want the owner's manual, warranty registration card, and all that. I paid $125 to have your used covers. I think I was generous when I bought them from you. Since I offered a higher price than normal, I thought you'd go the extra mile in fulfilling that order, man. Anyway, that's between you and I. Email me to discuss this. Later.
