This is a collection of 6 different 100% save games.
I am unsure of which safe-houses each saves are from, so I guess you'll just have to find out by loading each one up.
Each of the saves are 100% with all side mission (as far as I know) completed.
The most recent one that I have used is the file named 'SGTA412' which I know definitively is 100% completed.
I am unsure of which cars are saved at the safe-houses. I know this description is kind of useless but just think of it as a lucky dip.
If you have any issues, contact me!
