On the trip down from bonnie wee scotland where I bought the car I mananged 33.5mpg, which is better than I ever got out of my Mk4 Anni, and that was with a couple of 140mph burns down the M74.
The 4mo is 204bhp at the flywheel, and the 1.8t came in the 150 and 180bhp flywheel power too. So with the 4wd bogging it down you'll probably have the same amount of power as the later 1.8t's, but not the driveability or noise.
The wood trim is pretty easy to sort, I've bought some of that 3M carbon fibre vinyl to go over the whole mahogany effect pap. If you have a gander on eBay there is some of the 'net optic' stuff pops up every now and again, and that makes a refreshing change to the brushed aluminium from the Anni/32.
