I am looking online at the SEAT fixed price service. My cars a 2016 FR 1.4 ecotsi with 35k on the clock. The cars only done 4k since last service. I've fitted a pipercross element lately. They do a service for £179 or for £299 the service includes spark plugs. Obviously I won't need an air filter so is it best just to get oil and filter done, maybe plugs and that's it?? Does anyone know if the fixed price service is worth it?
