I've just been looking at a local cacher's stats and GC45MVG is coming up at -1327m! As the lowest point on the planet is the Dead Sea at -413 that can't be right!

The lowest caches I have seen are listed at fourthousandsomething meters below sea level. A cache is listed at the altitude of its initial coordinates. When for instance mysteries are listed far out to sea, they can get a very large negative elevation.

As this is a trad on Cyprus it's clearly an error.
Sorry, but this is very generic answer, not reflecting any details in the question. The elevation is wrong only on PGC and should be fixed (SRTM1 says completely different number -- see my answer).

This is a known issue of some of the caches. But as explained in the FAQ, there is usually nothing you can do about that:

http://project-gc.com/Home/FAQ#2384662308

We do not do manual changes in the data. But if you find an entry that seems to be off by a lot more than in other services, feel free to report it so that we can investigate.

But in your example, it looks like there is really something terribly wrong, because query on

http://www.gpsvisualizer.com/elevation

Coordinates (lat,lon): (34.85878 33.25958) FIND ELEVATION 425 meters (1396 feet) [data source: SRTM1]

That is a source, that should be used by PGC too. So this is something that ganja1447 should investigate further.
