I will probable get chastised for this but we have a new car wash in town, for $20 you get a months worth of washes! So I went through in the NA, it does a nice job. I have a SRT and XJS Jag also, Sunday afternoons was hand wash day for the three cars if they had been driven. I tend to use the NA because it gets the best mileage and is the least rare car, I have never taken the SRT or XJS through a automatic car wash because they both have the whale tail type spoolers and I worry about them being damaged. So does anyone use a car wash on the SRT's have you had any issues with brushes damaging the spoiler? I still will wash on Sundays and put some wax on the car about once a month if it is driven a lot.
