+1 on the camera lens, holy moley.

Nice find, man. If you never go fast, those old Rabbits will just go and go. Popular Science published a 75mpg rating at 35mph. Just puttering along.

The aero on those old Rabbits is just dreadful. I reckon virtually anything you do towards aero will reap huge rewards, especially in light of the engine's very modest output. You'll be pulling the power demands way, way down further into its sweet spot.

You might want to look into whether that engine has the upgraded head bolts. I understand that's a thing with the 1st gen VW diesel, head bolts loosening up and a resultant gasket blowout. [edit] Whoops, Cobb got there before me. Well, +1 on that too.
