Thanks all for your assistance...I have made my mind up..
After driving the 170 GTTDi today realised that I would hate to be stuck on the inside of one of these things, they are so basic (sorry GT Dudes). What a miserly array of features....even the 1.9 Match is better kitted out. It drove well though

Any hoo its a GTi for me!
Question is now which one...I can have an 06 Black with basic spec or £14.9k OR this tasty red DSG 05/05 for £14.6k Warranty up in May (if indeed it qualifies since the local VW dealer says its missed a service, now i have to check that the local garage used VW parts)......
Then there is always Mark_Eire and his fantastic example..but not sure my pennies will stretch and I have to get myself to Dublin twice...Hmmm.....
Funny when you start looking you think that these cars are easily available, then you look again and they just dont all stack up to your requirements.
So its the older, cheaper better specced DSG or the newer bare bones 06 (55) er at this time, perhaps I should wait a week or so and see what gets traded in as its the change over time?
