BTW, just stumbled across this.

17" packages $1350
18" packages $1650

Im not overly fussed if they come with crappy tyres first up. At least I get the wheels on my car for a price that doesnt't make the misses feint. I can always replace hthem for better later.

Also, no one really answered my other questions as to whats the most suitable size for my car.
