Part of the problem (and the appeal) is that they made the GTD far too similar to the GTI in terms of appearance and specification. So, it quite naturally gets compared to the GTI, and I actually don't see anything wrong with that given how closely they are related. You just have to read the reviews with a different perspective, and take notice about what actual owners and those who have driven it in the real world say. I'm sure that those who bought the GTD did so because of the lower entry cost, better fuel economy, lower road tax, and higher residuals. To that end, I highly doubt anybody who buys one will be disappointed, but when it comes to reviews, they are always going to have some bias. The GTD is obviously going to be a lovely car to drive, but it's also not going to have the "pep" of its petrol-powered sibling, or the street-appeal.
