How do you tell if the Repair Center sends you back a new 360?

So I sent my 360 in last Tuesday for the 5th time in 14 months. The past 3 have been for the same reason. Customer Support said when I send it in the repair people wil decide whether or not to send me a new one based on multiple returns for same reason. Well I sent my 360 in on Tuesday it arrived Thursday-Friday and the sent it back Saturday. Now it says 2-3 weeks for repairs and that was like 4-5 days. It should be coming in the mail today. Is there a way to check if its a new 360?

Any scratches on it would be the simple way, otherwise if you've written down the serial number, it'd be different on a different Xbox 360, otherwise I don't think there is a way really...

If it has a big-ass sticker on the bottom that says "Refurbished," then it's not new, like mine.

couple of ways

one different chipset

two different mfr date

three apperance of the console ie marks and stuff

Mark you name on the 360 on the inside metal in perminent marker before you send it off (you can buy the Microsoft Warrenty stickers off of ebay)

if it comes back without your name, check to see if its been cleaned off (by smell) because you can smell the solvants if they used any!

most of the time you WILL recieve a new 360, because its too much hassle to repair a old 1st batch or 2nd batch 360!

when they sent me a new one it said it was new in the letter that was attached to it...that and it looked a lot newer than my old one.
