Quicksilver
Newly installed. have about 1300 washes on it. i don't have any experience with the 5000, so can't make a comparison.
i drove through tons of washes before choosing the D&S Q.
PDQ is big in my area and i wasn't overly impressed with the M5 or G5. Most people i talked to like the laser 4000 better. power rains, vectors, mark1Vs and oasis were all tested on my vehicles. the new Q impressed me with its appearance and wheel blasters. my customers are equally impressed with it and they were mainly
PDQ users.
im still in the learning phases, so cant tell much more except to say its an awesome machine
