There is only one set of standard 5 spokes in the kit. It's not a Cooper S.
The rims I used on mine I "borrowed" from an Integra.
The assembly isn't too bad, the glass is the biggest challenge. You have to paint the black inside, and it's not well marked nor symmetrical. You have to be careful gluing it in. The top is a separate piece. The headlight and taillight buckets are almost too small, be very careful while assembling them not to push them too far through the hole. Mine were quite fun to build and worth the little extra effort.
Here are mine if you missed seeing them the other day:
This is the Maisto, these are the same rims that are in the Revell kit:
I've thought of stealing the headlights from this model for my Gulf car. The Maisto diecast has much better headlights than the kit.
