I'd also take my time creeping in to maximize the initial undercarriage and side blasters time.
The Sunoco at Merrifield (where I regularly go now). I always opt for the $10 blue plate special super deluxe wash with Rain-x clearcoat. Nothing's too good for my Ralfie
Btw Ralf's still at the dealership getting recoded/software upgrade (and other small warranty repairs). I got a Subaru Impreza 2.5i for the night, pretty entertaining little thing, grips well in this evening's rainy weather. Not bad, might consider for my civic's replacement, been having fun all day with it.
