Surprise repair bills
Suspension, brakes and timing chains rarely show on a basic check — then fail early and expensively.
Get MOT, tax, finance & write-off insights — plus reliability forecasts & money-saving advice. Buy with confidence using AI and official data
A Checkacar report can uncover:

A quick check tells you the car exists. It won't tell you what it'll cost you.
Suspension, brakes and timing chains rarely show on a basic check — then fail early and expensively.
An MOT pass only covers test day. Recurring advisories and worsening defects slip through unflagged.
Certain engines and gearboxes have well-known failures. Owners know. Sellers rarely mention them.
Asking prices reflect what sellers hope to get, not what condition and mileage actually justify.
Standard reports hand you raw fields. Whether to buy the car is left entirely to you.
Forums, recalls, owner reviews, service records — most buyers run out of patience before red flags.
From free basic checks to comprehensive AI-powered analysis. Choose the level of insight you need. Business users get exclusive discounts.
