I few years ago we needed a car quickly having just unloaded our car onto WBAC.com. It had just started to present auto gearbox issues which would have been expensive. Long story short, we arranged to meet dodgy Dave in a carpark near Brands Hatch. He was advertising a Golf Diesel Estate in the small ads. Whilst I checked over the vehicle just about every alarm bell was ringing and I definitely had the feeling that this vehicle was a wrong-un just like its seller. Still the paperwork etc all checked out and it drove well. Very well to be precise. As we needed a cheap car in a hurry our basic criterior was that it was both roadworthy and legal. It fufilled both so we bought it.
It turned out that said vehicle had be owned by a racing establishment near Brands Hatch. They had clearly been tinkering around under the bonnet with one mod being an oversized turbo charger. The result was that this lemon went liked a cat on fire. I said it was a lemon because it had clearly been comprehensively ranted uphill and down dale for most of its previous life and during the short time that we owned it the wretched thing presented just about every problem that a Golf was capable of.
It was a dog!
