So i had a good experience with this seller, bought a used cat from him for a great price, he responded immediately to my PM.
After some business the price was set, i paid, it didn't come (at first, turns out the person at the post office sent it to the address two blocks up from me) so naturally i thought i was getting scammed, but then i talked to him on the phone and straightened everything out. He did all the leg work to get this corrected and came when he said it would, smogged the car today and it passed.
I recommend buying parts from him and i know he has a couple of items for sale.
