Sorry to hear the sale isn't going to well John.
I have been there and done that successfully a few times now with 360's and don't take offense to what I say but I'm just being brutally honest with you.
Right off the bat for resale that blue Is in the same league as selling a silver car so it will ask less than others of other colours, reduce more price and potential customer size for manual, Modena (most want spiders), High milage, No mention of service recOrds, it is a 2000 model, the ACT is a bit hard to sell, you have had the car for a short time (just makes people wonder why selling so soon), also you are misleading with the milage. When someone posts the original miles on an import instead of the converted miles, first thing I think is something sus is going on, trying to hide something or just generally trying to misslead me or the car is a personal import or has not been complied properly.
Tweak up how the ad is written as after reading the ad it just made me feel wary of the car, be more specific about it's maintenance and honesty with the milage is better than putting the uk miles up.
Price wise it doesn't matter too much what you ask for it, but by the info you are looking at a sale somewhere under $120k even closer to the $110 mark for all the reasOns given above. Compared to what I'd on the market at the moment in my opinion you are asking too much from the get go.
The red/tan, black/tan spiders, f1, 2004-2005 models with lowish milage all the extras and complete history are still selling for around$155-$170k, but in reality they are what the buyers want, sorry to say your car is the opposite of what the general buyers are looking for. However you only need the one buyer who likes what he sees and is willing
Other than the colour which I think is a hinderance for resale, it just sounds like every other early model Modena asking
I'm pretty sure there is/was the same colour combo in south Australia, an Aussie delivered car, I was looking at it in 2010 and back then it was the cheapest on the market after being for sale for 9 mOnths and eventually sold, the last update for asking price was $170k when 360's were still worth $200-300k. I don't know what it eventually sold for in the end but it would have been under asking price, and it was same colour combo, aus delivered, f1 with 13 000km 2003 model Modena.
Good luck and hope I have given you something to consider when you update your ad. But definitely revise price, clarify service history, clutch read out if possible (as people never want to buy a clutch right away and will assume the worst), fix up the milage and probably take out the 5000km thing, it isn't relevant. Put in the ad it is a uk import just to show you arnt hiding anything, also did you realize you have a front challenge grill as well??? How many keys and fobs does it have???
