Not quite true.
European cars have terrible depreciation in the UAE because once the warranty/free servicing expires it's very expensive.
But Japanese cars hold their value extremely well. Six year old Prados with decent mileage are still getting 60% of their original purchase price. Four year old Accords and Pajeros others of similar calibre usually sell for 50-60% of original price. The OP has a Honda so he will get a good resale price in the UAE.
The big advantage of bringing his car to Dubai is that he can export it back to the US, whereas it's not really practical for any GCC spec car bought here.
I was assuming a comparison between the market value in the UAE of a US Spec Japanese car, and a GCC Spec Japanese car. I wasn't making a comparison between European and Japanese cars. I'm not sure where that came from, as OP stated (s)he has a Honda. Your point about Japanese versus European cars may well be correct, but I don't see the relevance to this discussion.
UAE buyers tend to assume a GCC spec car is better than the otherwise exactly equivalent US Spec car, and market prices of US spec cars are lower as a consequence.
Secondly, I think it is correct to say that cars in general depreciate faster here than in the US. A 2 year old car here is considered "old". That's not the case in the US (although of course in both countries, you take a whopping depreciation as soon as a car is initially titled).
So net effect is that OP should consider that moving a car to the UAE would depreciate its value a bit more than would be the case in the US.
Your point about being able to ship a previously-US titled car back to the US is correct, but some issues apply there:
First of course, you have to pay shipping to get it back again. That's another $3,000+ depending on shipping method. I'm not sure that shipping an even older Honda back to the US makes sense from a value proposition.
Second, I think it would take another depreciation hit once it is back in the US. If you told the average US buyer in the US that the car they are going to buy was driven for a number of years in Dubai they are going to assume that the dusty desert environment and heat here has worn that car more than if it had not been driven here. Most American buyers haven't been here, and the mental image Dubai conjures up is basically Tatooine.
BTW, I shipped a car from the US to the UAE, so I am not against the concept. I just don't think it would make economic sense for OP in this particular case. Of course, what might tip the balance would be if OP can get shipping and duty included in a relocation package. That's what I did, and then it might (just) make sense.
