lol well yes. I had the same prob as you when I bought my clio. My head gasket went 3 times, I bought it from Swindon and I live in Wales, although it was taxed and insured I still had to take it back and for to him, but in the end after the 3rd time I made him come and pick it up. Trading standards later told me that in the law it states "the consumer should not incur any additonal cost related with the breakdown of a product" So basically it's up to them to bring the car back and forth to you, not up to you to get it to and from them, as this would be costing you money.
Rather long message lol.
