i just got these gto dvd's and they have a really horrifying blend
hybrid pure interlaced vobs with lots of blends and ghosting
can anyone help me find a way to fix this?

Sometimes, sometimes not. Always need an unprocessed clip to diagnose though. (This looks like "funky blending", where the weights change across the frame; so far I don't think any perfect cure for it exists.)

hmm. the ranma masters are like this too. it's an antiquated telecine technique.
restore24 can probably be made to fix this, but (i haven't seen the vob yet), if it is the way i suspect it is, each field will persist over several fields, effectively giving you no clean fields to play with. in this case restore24 will just return the fields it considers cleanest, which is as good as you're likely to get.
if you can spare the bitrate (c'mon, how cheap are CDs/DVDs these days?), just encode it as interlaced xvid at full height, and deinterlace on playback (the xvid dshow filter does this already, and ffdshow can be made to). that's going to look the nicest of all your options, probably.

This is a question that I've been meaning to ask for a long time: what's the advantage in encoding interlaced in these cases? Won't the blending still remain?

and btw shouldn't restore24 be for PAL?

Yes, the blends will remain in your stream. The idea is that you won't notice it that much, since it is played back at 50/60 Hz. (Bob-deinterlacing for playback on your PC gives a similar effect.)

It will be played bach at 50/60Hz? Sorry for my ignorance, but don't analogue TVs display images at 25/30fps?

No. They will show you 50 or 60 (not sure whether they have pal or ntsc in Uruguay) half frames per second. I advice you to read the introduction of the analog capture guide:
