The title of your post got me thinking. Who makes the Best Daytona - Cost not an issue
As mentioned, a super franken with gen parts is going to put you into the thousands. Lets assume $4000.
Although I can only speak about my AD, you could presently pick up a SS Daytona for between $9100 used and $12,000 new.
Lets assume you can negotiate a new Daytona down to 10,000.
$10,000
-4000 (you would spend on super franken)
---------
$6000 remainder. FINANCE it. Many AD's aree offering 12/mo same as cash.
Still a bit $$$$ but you will have the real deal...
