you probably already know, but the 3 things you mentioned missing, LED's, storage and mats are all part of the chilli pack, and tbh, you never buy a mini without a chilli pack.. leasing the car is different i suppose.
I agree with most of the comments you made now you have had yours a month,
im on 1600 miles in 3 weeks, and im sitting around 40mpg indicated however in real life works out at 35mpg and im using Tesco super 99 RON.
i feel the engine is great and toquey but anything past 100 (private track session) and it runs out of puff.. whereas my previous Clubby S pulled hard all the way to max..
im still undecided about the ride too, i have the 17's and its like driving with runfalts tbh.. even though they are not.. but that might be to do with the increase in tyre pressures they use now?
