Sorry Carolina if you think I'm a jerk for 
saying but $500 is a bit high for that cel. It 
has some conditioning problems; the body posture 
is twisted with M. Vegita looking forward (his 
body should be forward) and it is severely faded.
It does have a background that might be correct 
(I'm not sure) but this is a limited plus. If you 
really want to sell this cel quickly I'd say its 
worth about $250 to $300. Not trying to rain on 
your day, just trying to give you a realistic 
opinion.    Sorry....
