It look's nice and tidy. The fuel will be negligible as it is the same engine just different map, if anything it would be better on a run as it's 6 speed. The tax I can't comment as mine is pre March 2001.
The benefits of the 180 is you get 312mm brakes. And the inside hasn't got the wood which you will be thankful for.
It won't have Recaro's but a set can be picked up on here easily enough,
At the end of the day you need to decide mate.
