I didn't take a huge amount of before pictures as, to be honest, I kept forgetting! Also, remember this took me less than 20 minutes start to finish, and I am sure you can get even better results with an extra 10 minutes buffing, but I suffer from buffaphobia so didn't bother.

Now I totally forgot to do before for rear, but similar to side doors in how dirty it was. Here is after shot:
Note: the dark mark down the centre right is my reflection, not dirt!

In summary, I am sure that the full wash, wax treatment is better and also I assume offers better protection, but I can't be bothered to do all that; I just want my car to look it's (near) best with minimal effort. Showroom shine gets these results in 20 minutes, and with no scratching, so I am more than happy.
My only issue with the product is the claims of 10-20 cars per bottle of spray. I would suggest in the real world it's more like 4-6, which still offers good value at £1.50 - £2.50 per wash with far above average results.
Hope this helps
