🔧 Retro Fast Fords Workshop Tip
If you’ve got £100 to spend, don’t buy the first shiny part you see.
Spend it on maintenance first. Fresh brake fluid, quality filters, good spark plugs and correctly inflated tyres often deliver a bigger improvement than cosmetic modifications.

Small, carefully chosen upgrades can sharpen the driving experience, improve reliability and prepare your car for future modifications.
