Gave the coupe it's first wash today after buying it a couple of weeks back.
It's only when you wash a car you start to appreciate it. To put this into perspective my last car was a Corsa Sport and the wife has a 5 door SXi. I'd wash the Corsa very regularly and the astra occassionally as the wife doesn't mind washing her car.
There is a huge difference between the two bodies, some things I'd never really thought about until washing them.
1 - I love the glass on the sides of the car. The way their is no metal seperating front from back is really cool when washing.
2 - The bumpers are slightly different, the coupe is a bit more, well bigger I suppose.
3 - All the body coloured bits like the roor rails and the bit at the bottom on the sides and the bump trim bit half way up the door.
4 - How big the window at the back is.
5 - How there aren't any windscreen washers on the bonnet on the coupe.
That's quite a lot, all the body coloured parts make a huge difference and the glass at the side is fantastic.
