Are the team stripes and the sponsor decals vinyl/peel off? or are they permanent?
Where is the car located?
How "new" is the new engine? How many miles since it was installed?
Well actually- Until your car sells, no one "knows" what it is worth. Until then, everyone has a personal opinion about what they
think your car is worth.
And opinions? Well, we all know about those...
Personally, when I see "best offer" in an ad, I instinctively think "Silent auction" - Here's a guy that wants to pull a list of bids together, so he can play them off each other and try to hand pick his buyer.
However, (and I'm speaking from personal experience here)- By and large, the greatest majority of Cobra replica buyers out there are guys looking for their FIRST Cobra; and to the greatest majority of them, the technical intricacies of a Contemporary, versus an ERA, versus an SPF, versus a Unique are going to be complete non-factors in their decision whether or not to buy a particular car.
To some guys, the fact that your car is a Contemporary might be less important than the fact that it is a 30 year old used car...
BTW- One thing about your car I do like is that it has a small block, which is much better suited and balanced with the Jag running gear (IMHO
And, just for disclosure, I'm not a potential buyer myself, but I am helping and scouting for a friend/co-worker who has been looking recently, and he is definitely a "blue with white stripes" kinda guy, so I passed your ad along to him this morning...
