[Fiesta_Man69]

So, the wash up appears to be that if you are a rational person who is able to reason for themselves, understands and has competed in motor sport and actually believe the multi billion dollar century old ford company might know what it's doing (not selling the tray on cls Lxs originally) then you will spend your money wisely elsewhere, be it on filters, semi slicks etc and just laugh at the aftersales claim.

Or, if you believe your fiesta is indeed a high performance, lowered, carbon fibred supercar that will gain from spending $130 on rice you will rush out and buy the tray...

Either way I'm ahead: sensible mods and a return of less than 6L means I'm laughing. The saying is a sucker is born every minute; just trying to warn that's all...
