Lol They don't check your knowledge about cars. If you were already knowledgeable, why would you join the forum in the first place?
They just check your english (very fussy and strict - no sms lingo, no single line answers etc) and they want a valid reason why you want to join.
Keep on trying. It took even as knowledgeable person as Dhirajbhai few years before his membership was approved at Team-BHP 2-3 months back.
Friend, this is not a Buy/Sell topic. So no need of locking. You have done it but there may be other members in future who want to do it.
