This slot started life as a plain silver Proteus Lamborghini Murcielago street car. I decided as I could not purchase a racing version of the big Lambo, I'd do one myself. I fitted the car with a Scalextric NSX rear wing as the NSX wing has a similar curve to the rear of the Murcielago, (see the second photo from the top). The rear wing was cut into the body of the slot which took a little more time and care than gluing it onto the body. The main benefit of fitting the tail in this manner is if the wing takes a big hit, the tail pops out and can be easily reinserted.
I picked the Jagermeister liver as it is straight forward and I had the spare decals at the time. Apart from the rear wing, the slot is standard. The Proteus Lambo makes for a great track car, particularly on my Carrera track. It's fast and handles very well. Unfortunately, Proteus stopped making slots a few years ago so these cars are getting harder to acquire.
