Salesguy drueling over my 1.8T 4 door

I went to my VW dealership today to look over their current Golf selection. They had a 4 door GLS TDI. I've been mulling over the issue of whether or not I made a mistake buying my '01 1.8T GLS 4 door instead of a TDI. Anyway, when the salesguy saw that it was a 1.8T Golf, his eyes glazed over and I could see the used car $$$$ in his eyes. Anyway, the TDI was pretty cool, but the power was totally lagging. This car was gutless. So, needless to say, I have a new appreciation for my 1.8T Golf and he reaffirmed that the 4 door was pretty special
