I'd be embarrased.
The befores are so-so and I'm not going to get them done professionally as it's just for winter tyres. Just a rub-down and rattle-can job and I'm not very good at that.
Or did you mean comparing the car with 18's and 17's? I can probably do that.
Should be fairly similar though the centre caps are different - not sure if I can swap them.
Can't quite decide on what colour to use though. Ford Moondust Silver is reckoned to be a pretty good match to most alloys and Halfords Silver (for wheels) I've read is quite grey - which actually might be a good thing as my car is Agate Grey.
