T25's

Mate is thinking of joing the up and coming cult of the T25 club, however was wondering what they are like on fuel economy.

I can not help as i have a 2l 16valve twin carb lump in mine doing around15mpg.

Can anyone give us rough idea on fuel return of all the different engine sizes available in these vans to guide him to what he wants.

1 more question, how slow are the 1.6 diesels, he wants something that will pick up speed reasonable and cruise at least at 75 - 80 mph down motorways.

Thanks for any help you can give
