1. Are the roads OK for my little suzuki?

I met a lot of people doing the Mongol rally - most of them were in two wheel drive old bomb and some of them made it through ( the ones who didn't were going way to fast for the conditions. - I think you will be fine, just keep talking to people about the roads in front of you and be prepared to make detours due to swamps / river etc and of course getting lost! (my track record for that was at least three times a day!)

2. How far are the petrol stations in Russia and Mongolia. My little car holds 11 Gallons about 41 litres.

I was on a bike with only 14l tank and I never had a problem - they are every 200kms. Get a good road map from any petrol station in Russia.

3. Is there a road to cross in Kazakhstan from Mongolia or we have to go back to Russia and then to Kazakhstan?

You have to go back into Russia for a 2-4 day trip through the mountains. I didn't do this but I have heard from people on the road that it was amazing!

4. Anybody has any electronic routes for this roads: Vladivostok,Russia and Mongolia please?

I don't - sorry...
there is an awesome map of Mongolia at the post office you can buy for about $20 us that shows you all the petrol stations and most roads no matter how small they are -its in English as well as Mongol. I brought the English version and translated the main towns into Mongol encase I needed a local to read the map. But I found most can sound out English oddly enough

5.How are these small rivers to be crossed in Mongolia? My car has 6 inches /11CM ground clearance. is this OK?

I ended up travelling with a old french police van and a camper van both only two wheel drive. I watch many times when they cross rivers / sand bowls. it was defiantly a good laugh. Just be prepared for a bit of digging - but that's all part of it isn't it?

Good luck with you planning.... Mongolia is one of my favourite countries ive travelled to date.
