You have 3 engines for sale, various new parts, freshly imported cars and you are wrecking another vehicle.
Sounds to me like you are a trader, and as such you must pay to advertise parts on SAU
Edit: Further inspection reveals that you are selling parts on this forum under multiple account names, both of which were registered on the same day, using Yahoo Hong Kong email addresses (R32 Autech and enr34)
Do not open another thread in the for sale section, or you will be banned.
