I find it easy:
"It is a modern replica of the iconic 1965 427 Shelby AC Cobra - this particular car is a 2008 backdraft with a Roush 427 engine and the T-56 trans. and I'm pleased it has the BMW M3 Suspensions and brakes to try to handle all the power - 540rwhp / 750 Nm to a 980 kg light car"
This way I have answered most of the questions that always followes...
If the ask how fast it is... : "If you ask for 0-100 km/h... It can kill you in less than 4 seconds"
And if they dare ask to "see the engine" : "no, they are not Webers... this is a EFI system where the intake is made to look like 4 polished Webers - better performance and keep the look "
