Booked in two minutes, paid when you collect
- Nothing to pay online. Settle up when you pick the car up.
- Free MOT retest within ten working days if it fails.
- Courtesy car when the job needs a full day.
- Anything extra found on the ramp comes with a call and a photo first, never just a bigger bill.

If the test turns anything up, you get a call and a photo before we touch it. Nothing is done without your say so.

Family-run, on the old depot yard
Cefn Derw is a family-run garage on the old depot yard outside Trefddangos, run by Emyr and a small team. DVSA approved MOT test station, hybrid and EV trained, and happy working on every make and model. Customers come from Trefddangos, Carmarthen and the villages along the Tywi because the work is honest, the prices are straight and nothing gets done without your say so.
Book online in under two minutes and pay nothing until you collect the car. Wait while your MOT is done, or drop the keys at eight and collect after work. If the test turns anything up you get a call with photos of the fault and a price before we touch it, and if the car has to stay in, a courtesy car keeps you moving. Fail the MOT and the retest is free within ten working days.
