I lost mine for 15-18 months, still waiting for the RTA to process all the fines and come up with a period cause i have lost count. I am keeping mine for sure and still have another year to go. Its not worth selling and buying one later on, you may get another skyline and just buy someone else's problem. If your car runs good and you are happy with it i would keep it. Save some cash in the year and build it up to a 300kw monster!
