Rob, I agree that it's a lot of money for a second hand replica, but the sum of it's parts is substantial!
Here's another Daytona currently for sale. A very nice car which would appeal to a different buyer entirely;
2006 CUSTOM KITCAR Private Cars For Sale in QLD - carsales.com.au
For $65K you get this spec interior
For $99K you get this
The Holinger trans and Motec gear in this one (plus Motec options, sensors, wiring etc) on their own would be over $30K, then there's the fire system, seats, harnesses, intercom, etc, etc, etc. Outside of this pic is the dry-sump LS7, 14" Harrop brakes, acres of carbon fibre and on it goes. I'm partial to performance over comfort, so the extra $34K in the sale price is a bargain. That said, I'm balking at getting my Cobra back together and registering it because I'm too tight to pay the $1K rego, so who am I to justify a $99K car???
