Need help pricing my BDR for sale

[NorCal Cobra]

Well, unfortunately the time has come to part with my beautiful sterling gray/silver striped Backdraft Roadster (2006 Build). With 3 and 1 year old son's added to the family, my priorities have changed.

I am asking for a little help w/pricing my beauty.

Here's what I got:

Backdraft Roadster 2006 Build
427 Stroker motor built by Smeding Performance in TX (564.3HP 564.3TRQ exact!!! w/ dyno sheets to prove)
TKO 600 Tranny 5 sp
4,100K papmered miles
Tonneau cover
Fully pollished 17" Halibrand style wheels
Full 3M paint protection
Body/paint/mechanical excellent condition
Passenger factory roll bar
SB100 (Titled as 1965 Cobra - No smog restrictions for life of car)

I want to sell it fairly quick, but I don't want to give it away. I was thinking $42,500. What do you guys think? I would appreciate any help.

Planning to list on CobraCountry very soon.

Thanks,

Mike
