Personally speaking, I sold my 289 FIA after moving from Washington back to Colorado for several reasons. Among them, out here there are no tracks in which to put the car through it's paces any where close to me as opposed to living in the Puget Sound region where there were 3 tracks within 45 minutes max. of my home. Here it is almost a 2 1/2 hour min. trip to the closest track that holds open track events. Driving in the mountains here is not really conducive to Weber inducted high performance engines either because of the altitude changes encountered. Webers are touchy.
The cruising season is short when driving a roadster here, even with the joke of top on, unless you like freezing your butt off
I'm getting older and the car was uncomfortable to drive long distances and most of my friends here are not Cobra owners, more into hot rods and muscle cars, so doing a Cobra cruise like we did in Washington was out. Yeah, there are Cobra owners here but those who are really active and do things are all in the Denver/Colo Springs area at min an hours drive south from my home.
I sold my Cobra but not a day goes buy when I wish I hadn't...until reality sets in...I did not want a "garage Queen" that only got driven on warm summer Sundays and I manged to sell it for a lot more than I had invested.
