Started so well and ended so badly. Just because you have a big budget DOESNT mean you have to use earth moves, drones, and tanks then blow things up to be funny.
I laughed the most at clarksons door not shutting properly, why couldnt they just fix the nova and do some more tests! dont mess with a winning formular. The previous "we all bought a cheap car" episodes were superb, the italian super cars, porsches, british layland etc etc and they didnt have to resort to blowing things up to be funny.
