I have a 2021 spec Q5 sline and wondering if any subtle mods are available or other owners have changed anything to make it look that little bit different?

Obviously you'll know any mods you do could void your warranty. 

That is The Audi cartel to make you pay through the nose for everything. I have a lovely Q5, but my warranty is probably void because I fitted wind deflectors on all four windows, made by Climair, the same company that make them for the VAG group. Side steps £1200, after market £300 fitted! Mudflaps £345 fitted, after market £54.99, for four pieces of rubber. I love my Audi, but the price for accessories is frankly obscene, and some will say if you buy/run a luxury car expect to pay, and I don’t mind that, and I can afford it, but refuse to pay it, so I WILL fit after market accessories, oh I have  a GB sticker on the tailgate and a National Trust sticker on my windscreen so I obviously doomed, as all these accessories will no doubt affect the braking and handling characteristics of my vehicle, what bullsh1t. 
Rant over!!!!!!!
