Fuel prices:
The fuels are separated by EuroNorm octane number at every tank station. You can buy 91 (not recommmended), 95 (for every car), 98 (communist cars need it

, and performance fuel (around 100, for street racing and stuff

), and diesel.
Today the actual rates were:
1EUR=251Ft
EuroNorm 91 unleaded 246,50 Ft/l
EuroNorm 91 for two-stroke 249,50 Ft/l
EuroSuper 95 unleaded 249,50 Ft/l
EuroSuper 98 unleaded 258,50 Ft/l
Diesel 218,00 Ft/l
Performance fuel is around 300Ft/l
so basically around 1EUR/liter
prices dont really differ at the various stations. If you come through Prague, I recommend you to take fuel in SLovakia, it's cheaper there.
Roads:
From Germany, any way you come, the only highway is the Budapest-Wien M1 highway, which is good quality but needs a road toll. it is 1200Ft for 4 days, and around 2500 for 10 days. If you come any other way you can just choose normal roads, speed limit is 90km/h, filled with trucks, and they go through every town and village, there aren't many roads around them.
Distances are not so big fortunately. Roads in this area are quite good, but still you'll be shocked compared to yours

Usually every car goes to a complete suspension change every 3 years.

Highways are quite new and well-maintained.
Traffic rules:
none I know of. You must turn on the lights outside the cities and villages daytime too, and each passenger has to use the seatbelt. In the city only the ones sitting in the fronrt are forced to wear it.
Speed limits are the usual 130/90/50, the price for speeding is 5000Ft if you go with max the 150% of the allowed speed, above that serious problems can occur

EC-cards:
Better restaurants accept it, but I dont think the shops not aimed for toursits do. You can pay with cashcard almost everywhere in the city, and almost every german bank has branches here.
paying with euro:
not typical. You can use it in the InterSpar hypermarkets, but they have a bad exchange rate. Money change offices are reliable, and widely available, they usually operate +-5Ft from the mid-rate, and no commission.
Food and drinks:
Dont bring anything, its much cheaper here (50-80%) of the price in Germany. In big hypermarkets (in a 5km radius we have Auchan, Tesco and InterSpar) you can buy anything you'd like to, even on sunday.
If you like you can eat in restaurants, but of course I provide the food and some good meals, we'll share the costs meanwhile/later. Shouldn't be too much. A quality meat dish with some extra stuff, slads, etc. comes to around 2-3EUR/person when I cook for 6-8 persons. Restaurant dishes start at 1.50 (chinese fastfood, I love it

), average is 4-6EUR, and the biggest and most famous restaurants end their prices at 20EUR/dish. But that's a culinary orgasm
Living place:
I live in east-western side of Budapest on the 8th floor of a block house.
Namely it's the thrid disctrict, address is: 1032 Budapest, Kiscelli street 8.
Just next to the right end (Buda side) of the ?rp?d-bridge. Everyone can tell you where the ?rp?d bridge is, it's the most northern bridge of the city.
I'll draw a map for you, detalied, but my phone number is +36/702212178, home phone +36/13881714 you can call me anytime, and when I know when you'll arrvie I can escort you from the edge of the city.
Emergency:
phone numbers just told

emergency numbers:
112 general help
104 ambulance
105 fire department
107 police
188 car club, instant service (ADAC partner)
these are all toll-free of course. maybe the car club isnt...
Sleeping:
sleeping bag is a good idea. The flat will be just ours that weekend, comfortable for 6 persons (3 double beds

), but I guess most of us are not that problematic, I like to sleep on the floor to. No air-conditioning, so my room is bloody hot for example.
We have another empty flat in the middle of the city (20min from here by car), there is place for additional 3-4 people (3 single beds). My father living also 15 min from here can support place for some people just in case.
You can choose a hotel of course if you'd like to, but dont forget the Hungaroring F1 event is on that weekend too so prices will be high and book your room in time. But sure I can provide shelter regardless how many of you come, I have also friends nearby
Border:
nothing special, things are easy and smooth now. Bring an identity card.
Questions:
looking forward to them
