edk, couldn't agree more.
Let me add in something here. Basically there are alot ppl first time owning UDM do not know anything about UDM at all. But sure enough they are pretty excited about owning one. While exciting that time, they tend to forget the problem with the UDM. How many people will take the time to know what is VIN numbers, fake AP, year of made? For example, There are alot more people don't know about this club although they own a BMW.
But one thing for sure, if you are first time owning an UDM, and lucky enough to see this message, i suggest you to hear all the sifus comment in this club and make your decision wisely. Infact, CKD and CBU or whatever specs that you can find is a same piece of machine. We call it 'ULTIMATE DRIVING MACHINE'.
