Fair price for Submariner 2006?

[warningshotz]

Hi Guys, I'm just considering to buy my first Rolex. I've found it on the internet, we would meet with the guy in the rolex store to proof the origin. Its a Submariner 16610 (2006). Bezel was replaced for a brand new, and the glas has two tiny flecks, not too visible. The glas change would cost $ 130EUR ($141). The watch itself costs 3955EUR ($4300). The watch looks worn, but in the rolex store they told me they can clean it dor me for $100 and it'll look like almost the bra s new. So it would cost me around $4.5K to change the glas and have to watch. Do you find it a good price? If I would buy it, and i would sell it in the future, would I lose money on the sell? Or will it keep this value I would pay for it now? Thanks in advance! Cheers, Warningshotz
