Okay, here is another issue, the original distributor of the bike that imported the vehicle did not pay the tax, and not willing to pay it, or delaying it. The problem is the dealer did not check this, bought a bike without all tax and other fees paid and without all paperwork in place. Now he is at the mercy of the distributor that is not cooperating or maybe even disappeared.... !
This happened to me and a friend, I am still waiting for my title from Papaterra, after more than 1 year - fair enough I wasn't there to chase it before for 9 months, but the last 3 months has only resulted in a number plate (just last month) and no title yet - which I think is terrible. They keep saying next week, like yours, and I have raised hell there with their manager, but still they can't do much unless the distributor pays the tax bill of 18% and other costs for importing the bike- shame on customs that let goods through with bribe and back doors.... (they of course deny this is the problem, but you can't tell me titles take 1 year to come unless there is a substantial problem like this).
My only hope is that there is an official registration of this bike somewhere, because they gave me the number plate and that electronic chip sticker (did they bribed their way for that, who knows !). I can also get insurance with the purchase document and together have something to show to AMET, though they never stopped me so far.
This could get really nasty, my friend's bike was over two years old and had changed hands twice and everybody was still saying the title is in the post (okay, he shouldn't have bought it without a title, but at that time it was only 5 months old and they said it is normal for title to arrive in 6 months !). He didn't pursue it though. His research later showed exactly that, no tax paid by importer so no title could be issued. He actually found a number for the importer but the guy on the other end said he is not going to do anything about it, tough... !?
Finally when he tried to sell it, no title still, ran into problem. Well, he found the lawyer who had friends who had friends who had.... you know what is like !, to claim the title was lost - with records somehow suddenly appear on computers (hello!), so a copy could be issued ... !!!??? for the appropriate cost of course...! (what a country)
I have threatened Papaterra to take the bike back and refund in full, but they just laugh and say don't worry, the title is in the post. I guess ultimately need a lawyer involved, but that would mean a lot of costs waste of time and who knows, to litigate a minor civil dispute like this could take ages....who cares you have no title for your bike, I bet 50% of bikes here don't have one !
Good luck.
P.S. Someone mentioned check that the bike has a title before buying, but no new bike in the shop has title, they need to request and register it in your name, dealers don't get and put a title in their name (unless it is sold before maybe !). Maybe it is different for cars, I don't know. But I think it will be harder to import and slip through a car without paying tax... ! (but in DR anything possible !).
