I have just picked up an old Fighter Buggy RX (Correct me if I am wrong!) from a boot sale. Not bad for £3 including an Ansmann quick charger and 2 batteries! I'm going to restore this one as a runner for my 8 year old - should be a good buggy to start with. It has electrics and it all appears to work ok. The main issues it has are a broken rear shock mount and the rear tyres are completely shot.
