Actually 40 MPG isn't as bad as I thought. Just done a conversion on Google and it equates to 5.88 litres/100 Kilos .... pretty much the same as my MKII 1.9TDI Octy (usually 5.6 - 5.9). As I work eveninigs/nights and tend to potter around within the speed limit I'd probably squeeze a bit more out of it than the average amateur private motorist. Good advice on the glass BTW, TD... something one could easily overlook.
