OK, just saw another thread related to this. It seems that the car is a BMW M3 GT TS-4N Pro V2 - I think. It is for sale at
http://www.sussex-model-centre.co.uk for £239.99, fully assembled (does that mean I can get it cheaper, unassembled, elsewhere?) The spec, from their website, is below:
• 100% Factory assembled
• 2 channel radio installed
• Painted body
• Strong, fibreglass reinforced composite parts
• Super low centre of gravity
• Double foam air filter
• Metal bushings
• Steel drive cups and dog bones
• Roll over bar/ car handle
• Colour coated springs
• Triple belt, four wheel drive train
• Performance metal manifold & tuned pipe
• PRO 12BXS pull start engine
• Blue anodized chassis
• 2 speed system
• Metal shock absorbers
• Full ball bearings equipped
Is this good & what are the chances of the DeAgostini one being of the same standard, and not less?
