@AKCH the OP just wanted a ballpark figure for an FEI Grand Prix show jumper so she could tell her non-horsey friend when they go together to watch a Grand Prix.
I get asked by colleague / friends all the time about how much the horses they see at the Olympics or on TV from Spruce Meadows cost - and I always say “millions”. There was an interview with Mclain or Beezie a few years ago where it was mentioned it was hard to find a 1.60m jumper for less than $3,000,000!
