Build by the Swiss Company "Lambo-MotorAG" in Basel - Swizerland, #4808 chassis has already been shown on the Geneva Motorshow - march 1971.
The work done is not a Factory modification but a post-production one - so belongs to every-one to estimate its corresponding value...
It is similar in modifying a Miura S into a SV version, or also a Daytona Coupe into a Spyder version - this by a skilled workmanship.
These examples corresponding in modifying cars into other existing versions - instead of #4808 remaining a hybrid work, depending only on its creator imagination.
Difficult to give a value to such a car, fore sure a lot of work done on it ... let each of us have its own idea..
After having been modified into a spider (with removable roof, Gotti-style wheels with low-profile tyres, various bodywork modifications : front spoiler, integrated rear spoiler (similar to Porsche 959 type), widened rear fenders,...) this Miura has been shown during the 1981 Geneva Motorshow - sharing the official Lamborghini Stand with 2 Countach LP400S models and 1 Jalpa 3500.
Its white painting explains it has been sometimes called the "White Giant".
Later partially modified again (normal SV wheels fitted back, front and rear spoilers removed,...) this car has been repainted in metallic silver, and more recently in Miura "lime green" (Cf. car displayed on Lecocq stand during 2008 Retromobile Motorshow in Paris)
