Thanks for the pointer, I'll be ordering shortly.
If I had the money I'd defiantely get the Aero kit, but funds are a bit limited at the moment so I've stuck with the 'cheaper' cosmetic updates

.
So far I added the Union jack roof and the John cooper signatures. The white caps on the alloys are not actually painted, I bought some white plastic nut covers off ebay and put them over the existing wheel nuts. Only cost a couple of quid and I'm quite please with the result.
The only other mod is the Harmon Kardon ipod system I added, which again was fairly cheap (less than £30) but is well worth the money.
Only had the car about 4 weeks now, but customising is so addictive on it !!
Thanks again for the comments,
Rich.
