[ej25#headgasket]

 I am the proud owner of a Subaru Outback 2.5 2007 SE. and love it. But I do have a few gripes about it. I cannot seem to be able to Buy OEM splash guards / mud flaps / gravel guards you choose. I've seen some for sale at S Pecht subaru stealership £65 plus VAT and delivery for the front set and the same for the rear totaling £171. It seems a little steep considering the choice for every model after mine on eBay / Amazon etc any one know if there are any reasonably priced ones anywhere els?
