4-Only you can ride/drive the vehicle inside the country.
5-If you want to leave the country without your vehicle:
Thats a very long story and just for 30 days permission.
You must fill a form to keep it staying inside the country for the permitted 30 days,apply to a customs management,do the paperworks,leave it at customs parking area and get the written permission..you must extend this formality before the time expires each time.If still!! interested, can send you the application forms online..Also available somewhere on hubb.
As far as I know, the fee is 8 usd. per day in istanbul, 5 usd. in trabzon and dog biscuit customs but no space available in big cities as all are full of vehicles with unextended permissions..After 5 staying years,government sells them in an auction.
6-SO WHAT TO DO FOR A SAFE AND CHEAP SOLUTION.
A-Doug s camp in Bulgaria is the best solution since many years,also a good meeting place before heading to east...Ivo is a great guy..I know 2 transalps are currently in winter sleep there!!!
B-Friendships and road angels..
During HUBB meetings or while on the road, or if you visit a local bikers club in a country, you will meet many great local friends, road angels to share the spirit of adventure travelling,exchange experiences and even to get some recommendations...This is a great world and most are also on HUBB..
Several Turkish friends also did so even in asian countries last year.
Hope you will meet them very soon for a solution outside Bulgaria.
All questions about Turkey welcome.
All the best.
