is this a fair trade?

[SubKing]

hey all,

i really dig the 5508 rolex sub and have been thinking about getting one..

I wanted to know if trading my SS daytona black dial V serial for an even trade for a 5508, fair condition original gilt dial and hands, but it does need some work and a service.

I really love this watch but i don't know if i should hold on to by daytona or do the trade?

when it comes to vintage, im kinda new to it, so im unsure if this would be a fair trade. i know what to look for as far as service dials or relume ect..

any input would be great.
