Hi..MJJ
Superformance makes a fantastic Cobra replica. The one you picture, however, appears not to have an engine in it. I'm assuming this b/c it appears that the
oil cooler is not hooked up and the front suspension looks to be uncompressed. Such is the case normally with an SPF as they come from South Africa in this state with the customer specifying the Engine/Trans options to their preference. I'm assuming you know this already....but I just mention it b/c of not knowing how deeply you've enquired about the car you have linked in your first post.
Others here have stated their preference on the wheel options, and I am more of a traditionalist when it comes to the appearance of the cobra replica, so I agree to the 15" wheel options that are available. You could either put an FIA style pin drive wheel on the car if you want a very early 427 look, go with the standard Halibrand replica wheel, or go for the more rare sunburst style that have also been reference here by Tim in Post #12. The disadvantage with the traditional look is that there are not many good tire choices for 15" wheels as there are with the taller 17" wheel that appears to be on the car in your link. You will have the option of more modern compounds over a wide range of tire manufacturers if you stay with the non-original appearing 17" option.
Also, you didn't need to explain yourself on why you prefer to own a cobra with an undercar exhaust, but I hope that when you finally get one in your garage, that you and your family enjoy it for many miles and many years. I'm sure your dear son will have trouble removing the smile from his face when his dad takes him for his first ride.
