It cost £350 back in 1984!
Just a lucky kid i guess.
When you consider the quality of some BMX bikes today (e.g. Supercross and Redlines around £400-£450), inflation doesn't seem to have affected the BMX market that badly.
I remember my dad buying a Golf GTI in 1988 for £10,600 and they're about £21,000 now!
By the way, really nice build that Munners. Skyway TAs are class.
