When I bought my acura TL-S they had to have it for week to do some work (bad seat, stereo and headlight) they gave me a CL-S that was NASTY - (used lot) I could not stand it - when I got it home I hit the interior (which looked like someone covered it in pancake batter..) with Meg's 39, cleaned the leather with Platinum Leather Cleaner, used my Oreck on the carpets, then PB's Natural look and Platinum leather conditioner - then I hit the exterior - (it was white) 3M Finesse It II, 3M IHG, AIO then UPP - did the usual wheels and tires clean and dressed... took me a few hours the Saturday I got it and I didn't do anything else to it until I gave it back....when did the service manager could not believe it - when they pulled my car around, my loaner looked better than my brand new TL-S..boy was I P*ssed...(they wash cars when you bring them in and they do a horrible job!! Since that time I have insisted they not..ever!)..
