The one i've been out in is a 54 plate.

Facelift was slightly more powerful IIRC, original one was 197bhp, newer one was 202bhp

Front lights are the only thing that stands out for me with regards to other differences, but tbh i havent looked that closely

They don't have fog lights and AC as standard. For 17k i'd be fucking pissed off at that. Even though i don't use my front fogs out of principle, but cars look bare without them
