Hello Paul, I took my Toyota Mark X for a routine service at a certain garage, but when I picked it up, the ride felt softer and the steering lighter. A friend later told me my alloy rims might have been swapped for cheaper ones. How can I tell if my original parts were stolen, and what parts are most commonly swapped without the owner noticing?

Hello Henry, welcome to the club of motorists who have driven out of a garage wondering, ‘Wait a minute, was my car always like this?’
But before you storm back into the garage demanding answers, let us separate suspicion from evidence. A softer ride and lighter steering do not automatically mean someone has been helping themselves to your car parts. Tyre pressure, wheel alignment, suspension work and even new components can dramatically change how a car feels.
That said, motorists should not be naïve. Your car is often left in someone else’s hands for hours, sometimes days, and you should know what happens to it while you are away.
Let us start with your alloy wheels.
If you think the Mark X came back wearing different rims, look for photographs of the car taken before the service. This is why I always advise motorists to photograph their cars before handing them over to a garage. Take pictures of all four wheels, including close-ups. Scratches, dents and unusual marks can be useful identification features.
Compare the spoke design, colour, size and general condition. If the old wheels had a distinctive scratch and the new ones look suspiciously perfect, you have something worth investigating.
There are also markings on the inside of most wheels indicating their size, width and offset, and sometimes the manufacturer. A reputable tyre or wheel specialist can remove a wheel and check these markings for you.
Do not forget the tyres. Check the brand, size and tread. If you went into the garage with four matching tyres and came out with two different brands, ask questions. The same applies if nearly new tyres suddenly look considerably more worn.
What about other parts?
Some components can be replaced without the owner immediately noticing. Batteries, air filters, spark plugs, brake pads and suspension components are among the parts that may be changed during servicing. There is nothing automatically wrong with aftermarket parts, but the garage should tell you what it has fitted and you should have authorised the replacement.
Some motorists also worry about catalytic converters because of their value. These can be targeted by thieves, although their removal or replacement would normally leave clues that an experienced mechanic can identify.
The golden rule is simple: know what went into the garage with your car.
Before handing over the keys, record the mileage and take photographs of the exterior, wheels, dashboard and engine bay. If you are leaving the car for major repairs, document expensive or distinctive components. It takes five minutes and could save you a serious argument later.
Insist on a job card showing the work to be done. If a part needs replacing, ask what is being installed and why. For major components, ask to see the old part when it is removed. Your invoice should also clearly indicate what parts were fitted and what you paid for.
As for your Mark X, I would not accuse the garage just yet. Take it to another reputable mechanic or Toyota specialist and ask for an independent inspection. Do not simply tell them, ‘I think my rims were stolen.’ Tell them that the car feels different and ask them to inspect the wheels, tyres, suspension, steering and brakes against the correct specifications.
If something has been changed, they should be able to identify it.
And next time, remember: trust your mechanic, but photograph your car first. Good garages have nothing to hide, and good records make it much harder for anyone to pull a fast one.
After all, you took the car in for a service. You should not have to leave wondering whether it was serviced or slowly dismantled.
