Pre Purchase Inspection

Having a car is a necessity in Dubai. But when it comes time to get a car, the question is old or new. New cars are obviously expensive and come with contracts and warranties, but there’s a misconception that buying used is risky.

If you are looking to buy a used car, get a pre-purchase inspection done so there are no expensive surprises, and you can be assured that you are getting a good deal.

We have a detailed pre-purchase car inspection service where our certified technicians have a vehicle checklist that includes a 24-point car inspection, checking mechanical issues, external and internal body damage, and then we share a detailed report, so you know exactly what’s wrong with your car.
