Throwing huge sums of money at stuff, before paying for the really important things, is one of the reasons i drifted away from motorsport. Even in the middle of the ladder there was re-mortgaging of houses going on, divorce, bills not being paid etc just to do 30 mins of racing, one weekend of the month, in front of one man and his dog.
Even worse are the money bag clowns who spend 100's of thousands, of mostly their own(well...a banks money) to run cars in the top class of the British Hillclimb Championship. Barely any spectators these days and hills in the UK are like 20-40 secs. I think the longest is Doune, up in Scotland. On the continent the hillclimbing is a different thing all together with really long climbs, thousands of spectators, TV coverage, and sponsorship can pay for alot of it. Drivers over there can become household names as it is just a much bigger thing.
Personally; i thought it was ridiculous. The UK hillclimbers are never going to be famous outside of a niche group of fans and drivers and you might think that they were doing it for the fun of it, but another reason for walking away was there weren't that many people who were having fun. Even at the bottom end there was misery because there wasn't enough money to buy new tyres to beat Richard, from Bognor, or Fred from Hull, or misery because the spanking new engine, that was the ticket to beat them, has just shat itself.
The guys i worked for were definitely in it for the laughs and only spent what they could justify. Even the minted chaps would stretch sets of tyres to the absolute end and be really choosy about what events they did. Family and bills were given top priority.
My early days helping a fellow apprentice, with a mk1 Golf, were all done on a budget and laughs were the priority. It was a very strictly controlled series, to keep costs down, but all it seemed to do was raise the bar for the cheaters who were another reason for stepping away. It was bonkers for a series that not that many people gave a sh!t about. My mate bought himself onto the top of the podium, but that didn't last long as the car got written off, in a motorway crash caused by another car that bounced off a guardrail, on the way home from a day racing. At least that paid out so things could carry on with another car.
I dunno. If £550ish is to the buyer what £50 is to me then fine. If it involved any kind of debt, for what was some grubby old tyres, then they are a fool and nobody should be impressed.
