I own a 911 C4 cabrio 1990 -beautiful dark silver /titanium color...in A-1 condition certified, new tires etc. Its sitting in the Netherlands where I used to live (I am now in the US in WA) I have tried to sell it for over 6 mos and no bites - as there seems to be a glut of porsches for sale in Holland. I even lowered the price to 'very fair'. So, I'm getting really frustrated...and have decided that I want to consider importing it...What do I need to do? Went to the NHTSA site...read all the info and I'm more confused than ever...would appreciate some feedback...I can't sell it and I can't drive it....help!
