When you bought your car, you probably focused on the monthly payment. "Can I afford £300 a month?" is the standard question. But dealers knew this, and they used it to their advantage.

## The Monthly Payment Trap
Dealers often manipulated the interest rate (APR) to hit a monthly figure you were happy with, while secretly maximizing their profit.
- **Example:** You could afford £300/month. The car actually cost £250/month at a fair interest rate (e.g., 5%).
- **The Trick:** The dealer sets the rate at 9%, bringing the payment to £290/month. You think you got a deal because it's under your budget, but you're actually paying £40 extra every month, purely for their commission.

## The "Flat Rate" vs. APR Confusion
Dealers sometimes quoted "flat rates" which look lower than APRs but don't include compounding interest. This made expensive loans look cheap.

## Reclaiming What's Yours
These tactics weren't just aggressive salesmanship; in the case of DCAs, they were often unfair practices that breached regulatory standards. You have the right to reclaim that "hidden" extra cost.
