Re: Taking car into Turkey
My understanding is there is no limit as how many times you can bring your car into Turkey, definitely if it's out 185 days then back again.
Yes, you yourself could have entered Turkey in a different car. The 185 day rule does not apply to you as you were never here in a car in your name and not stamped into passport. The 185 day rule is for the car and person together but as you are retired, you are good. Your wife maybe different as she needs to prove she is receiving a pension from somewhere to prove retirement. This would mean the 185 day rule applies for her if she cannot prove that she is retired. This is ridiculous as some people might own several properties and receive rent revenue from them as income instead of a pension.
I found this information at Fethiye customs with a Turkish/English speaker. Fethiye customs suggested we try Dalaman customs as they are more experienced in these laws so we went there and they confirmed everything.
They also said there might be more changes a foot in the next month or so but didn't say what that would be.
Good luck and have a safe journey. Beware of the weather, we got stuck two days in Gelibouli in the snow
