If you're going to do some amateur detailing yourself (without going way overboard), i'd recommend a decent iron decontaminator (something like iron X) for when you get it home, and a sealant that is easy to apply. I'd recommend G-Techniq C2V3 to the external surfaces of the car and wheels - relatively cheap, easy on, easy off with the excess and you don't have to watch getting it on unpainted plastic surfaces. Beading is excellent, shine is excellent, it lasts a good 6 months before the effects start to diminish and muck comes off very easy (brake dust finds it hard to stick to the wheels).
