£300??? Not in the UK, I was struggling to sell mine for £100 in the end went for £80..... And it was in a really good nick!
Pricing these is difficult, depends on condition and mainly your location, I guess there are not as many EK9s in Malta as there are in the UK.
I'd say £100 for the mats if you're lucky and they are absolutely mint, but more like £60 - £70. I chucked mine in our 4x4 lol. Go on ebay and check how much this stuff sells for (please note I wrote sells, there are loads of dreamers on ebay...). Just do a search and tick "sold items".
