I was lucky enough that Richard Hammond did one of the best Top Gear review segments ever in my opinion, on the GTN. The weather and filters made it look menacing, the music, his genuine love of it and the iconic quotes and references, and then the noise... together it made a really rather special piece of television, and the car just happened to be centre stage.
I must admit I still pinch myself a little, when I go in and see it - the only thing I haven't done yet is drive it due to the weather, its going to be a long few months till spring...
I can identify with that - it was the X-Car video in London that triggered the purchase of the Coupe. I still watch it from time to time now.
I know the video you mention with Hamster and the GTN, it was a belter. I was looking for the first Morgan we bought, the S2, at that time. The S2 was £40-45k but there was a GTN for sale at £80k at that time. I spent ages trying to work out if I could tweak the budget and was not experienced enough to know the difference. The S2 proved a good starting point.
