KEY POINTS:
They are calling it the ultimate bonding experience - the sale at this week's Sydney Motor Show of "father and son" Ford Shelbys.
Auction house Shannons expects dad's car, the 1967 Shelby Mustang GT350 Fastback, to fetch between A$200,000 ($234,000) and A$240,000 ($281,000). Junior's pedal car, styled on the 1965 Shelby GT350 and signed by US motorsport legend Carroll Shelby, is likely to sell for between A$600 ($702) and A$1000 ($1170).
The left-hand-drive Acapulco Blue and white road-going Shelby has a well-documented history and was restored in the United States before being shipped to Australia this year.
Unlike the original raw, track-orientated 1965-66 Shelbys, the 1967 Shelby range marked a shift in emphasis towards a more civilised, better equipped and easier to drive vehicle, designed to appeal to well-heeled professionals rather than weekend warriors.
Based on the '67 Mustang, the Shelby GT350 was powered by the classic K-code 4.7-litre V8 for 1967, using an aluminium intake manifold and uprated carburetor to develop 228kW (306bhp). The Fastback is equipped with optional three-speed C-4 automatic transmission.
The pedal car is designed for children over three years of age and also comes with a certificate of authenticity from Shelby and Ford.
It is 99cm long, 46cm high and 40cm wide, weighs 9.5kg and comes complete with chrome hubcaps, solid rubber wheels and adjustable pedals.
