AQA GCSE question, need help!?

Hi. Okay first off, i'm not asking anyone to do my homework! I'm just having a hard time with this question, so i'd like if someone could just help me out a tiny bit.

So, the question i have to do it on this article:

This giant yellow Lego brick on wheels would leave members of the public in stitches after seeing it on their way to the shops, so it’s probably a good thing this US exclusive vehicle has never made it over into the UK.

Scrape off the yellow paintwork, and give it police colours, and you could use it as a battering ram to get through the front doors of criminals' houses, or a stage prop for the latest Rihanna concert. But as a car for getting A to B, the Scion seriously sucks.

It's a rare error from Toyota, and certainly a memorable one. But we forgive the Japanese giant for giving us the environmentally-friendly Prius and the cool inner city car known as the iQ.

I have to find a couple of language techniques and grammer features and explain how they work.. So far i have

1) Sentences starting with 'but'

2) Metaphors

But i need atleast four... some pointers please? Thanks, all help appreciated
