Customer reviews

What do our clients say?

“Our vans are serviced overnight and back at the depot for the morning shift. The monthly report per plate finally shows us where our maintenance money goes.”

Sample client

“Another garage wanted to replace the turbo. Here they measured first, found a split intake hose and I paid a fraction of the price. The quote came by SMS before they touched anything.”

“I followed the whole repair on the website with my job number — diagnosis, approval, repair, road test. The van was ready the next evening and the old parts were waiting for me in a box.”

Frequently Asked Questions

Common questions

Can't find your answer? Contact us.

What warranty do you give on parts and labour?

All repairs carry a 2-year / 40,000 km warranty on parts we supply and on our labour; engine and gearbox overhauls carry 12 months / 30,000 km. Wear parts such as pads and wipers are covered against defects, not normal wear. The warranty terms are printed on your invoice.

Genuine or equivalent parts — what is the difference?

Genuine parts come in the carmaker’s packaging; OE-quality equivalents are made to the same specification, often by the same suppliers, and cost less. We never fit unbranded low-quality parts. Your quote shows both options with prices, and you decide.

Will servicing with you affect my manufacturer warranty?

No — as long as maintenance follows the manufacturer’s schedule with parts and fluids of matching quality, your warranty remains valid. We stamp your service book, record the oils and parts used on the invoice and keep a digital record you can show at any time.

Do you offer a replacement car?

For repairs that take more than one day we provide a courtesy car, subject to availability — please mention it when booking. Within the city we can also collect your car and bring it back after the service.

How does online job tracking work?

At intake you receive a job number by SMS. Enter it on our “Job status” page together with the last 4 digits of the phone number you gave us, and you will see the current stage — diagnosis, waiting for approval, in repair, road test or ready for pickup — plus any notes from your technician.
