I have 4 cars. My Limited goes to the car wash (as much as 2-3 times per week). My wife's Mercedes goes through the car wash (maybe every other week). My 2 Porsches get hand washed, by me, about every 3-4 weeks (only driven on weekends, no rain, stored in heated garage from late fall to early spring). I have all I can do to keep my 2 toys hand detailed.
I do clean my Limited's windows, apply leather conditioner, vacuum, and I waxed it with RejeX when brand new. My truck is spotless.
