I bought my Ferrari 360 Spider from a friend on the mainland, and today I successfully registered it in Honolulu. I had great help and good advice from my neighbors on this forum, but I found the whole process to be challenging. My goal, and I suspect it would be yours too, was to only wait in line once at the Satellite City Hall. I was successful in that, but again, I found the process complex and challenging. I thought I would write down the necessary documents you should bring with you while I can still remember them! Please note that in Hawaii vehicle registration — although technically a state process — is handled by the counties, so each county is different. I can only describe the process in Honolulu. The forms I mention finding on-line are generally found at: Forms You will likely need the following documents and forms: 1. A current Hawaii Insurance Identification Card. Rather obviously, this means one of the first things you must do is insure the car. But you were going to do that anyway, right? 2. A Hawaii State Safety Inspection that shows the car failed the inspection for only one reason — lack of registration. Please check this! My document originally listed another problem (“warning lights” which, as it turned out, was a mistake. When asked, the safety inspection station folks reprinted it showing only the registration as a problem. If I had not noticed this, I would probably have ended up standing in line twice. So, check it. 3. Foreign state registration. My car was registered in Montana, which apparently has perpetual registration (so, no end date — actually the end date is shown as “Valid Through Date 12/31/9999”. This caused some minor confusion but it worked out. 4. Foreign state title. I had the seller notarize the transfer of title. I am not sure that is legally necessary, but it can’t hurt. They kept the foreign title, so if you want a copy to keep, make a copy in advance. 5. Bill of Sale. Again I had the seller notarize this, too, and again while that may not be legally necessary it can’t hurt. I used the standard Hawaii form, which you can find on line at the Honolulu Department of Customer Services web site. It is form CS-L (MVR) 40. The notary was in Virginia but simply used the Virginia stamp and signature. My thought was the more familiar the form, the less likely to be a problem. There was no problem. Again, they kept the original Bill of Sale, so if you want a copy, make a copy in advance. 6. Waybill showing date of import into the state. In my case, I had an Air Waybill, which again caused some confusion. They solved this by having me fill out form CS-L(MVR)19, Vehicle Arrival Certification. If you ship your car by sea, you probably won’t need this. They see those forms all the time. Air Waybills are unusual. My Waybill showed the date I picked the car up, the Arrival Certification wants the day the car arrived in Hawaii. Again, a minor but potentially significant difference, particularly if you are getting close to the 30 day limit. 7. Toledo Scale Weight Ticket.nMy neighbors on this forum had wisely advised me that they might not have the weight for our cars. So, I went by Toledo Scale at 1914 Has Street and paid $30 to have the car weighed. Again, my goal was to only stand in line once. It worked. I am not certain, but my impression is that they did NOT have the weight of the car. So, even though it was on the foreign state title, without the Toledo Scale weigh ticket, I might well have ended up standing in line twice. 8. You will need to complete a Form G-27 Motor Vehicle Use Tax Certification. If you have bought your car from a friend, it is likely a “casual” sale. If you have bought it from a mainland dealer, and if you did not pay a sales tax in the state in which it was purchased that equals or exceeds our Use Tax, you will likely need to pay the Use Tax. You should look into this with some care — the Use Tax if due can be expensive (in my case I think it would likely have been in excess of $3,500). The instructions are complicated. I needed to go to HAR 18-238-2 to check the definition of “casual” sale. You may (or may not) fall under some other exception, listed in the instructions for Form G-27. You can find all this online, which is a big help. But this is complicated, you need to get it right, and there are penalties for getting it wrong or misrepresenting the type of sale. 9. Finally, you will need a Form CS-L (MVR) 1, which is the basic Application for Vehicle Registration form. Oddly, it is not available on-line, and I did not see one out when I walked by a Satellite City Hall. I asked the dealership, where I was having the car inspected and annual maintenance performed, and they were kind enough to provide me one. So, I had it filled out and signed when I got in the line. Again, the goal for me was to only go through the line once. I don’t know what would have happened if I had not located one of these forms — would they have let me fill it out at the window, or would they have given me the form and sent me to the back of the line? I didn’t want to find out, so I found one and had it filled out and ready to go. With all this stuff in a folder, I went to the Downtown Satellite City Hall. The line was short and the staff was pleasant. Even with everything prepared in advance, it was a complicated process that took about 15 min. or more. At the end of the process, I paid about $300. Please note you need cash or a check — a credit card will not work. After payment I got a shiny new Hawaii title for the car, a registration certificate (which is kept in the glove box with your insurance card and safety inspection sticker), and two new license plates — front and rear — with a current registration sticker to put on the rear plate. And yes, I plan to install both; I don’t want to give any police officer an excuse to stop and ticket me for not having a front license plate. With all the goodies from Satellite City Hall, you then need to go BACK to the safety inspection site, with registration in hand, and get a clean safety inspection (which should not be an additional cost, but is an additional step). I thought this was a pretty complicated process. If you are registering a car, there are a number of reasons you may have a different path to follow. So, for example, if you are just bringing your car from the mainland with you when you move to Hawaii, things should be much simpler. Maybe! In any event, I hope this may be of help to someone, sometime. And thanks to all for the good advice given previously on how to do this.
