i arrived at 8 last year, got breathe checked for alcohol every 5 yrds!!! and wrist banded, and told i wasnt allowed to drive and all sorts of pants, even though they've just seen my clearly driving in....
Hmm, ive removed it, all i really notice is noise at say, slow moving, like 5mph... thats it really. And i got mine wet with the jetwash, and cba to wet vac it so removed it... it looks clean underneath so im happy, but yeah if it was immaculate id leave it in
Its not necessarily the camera at fault, maybe change a few settings on there, and Photoshop works wonders on photos. Give that a go before buying a new camera?
