Since getting my first VX 2 months ago, I have cleaned it extensivly (altho it was already in like new condition). I delayed touching the leather seats because I knew what I wanted to do, but was hesitant. Years ago, an old timer told me his secret for preserving leather. He didn't volunteer it, I had to pry it out of him (I don't know why). His name was "wild" Bill McCain of Erie Pa. and his nickname was "Cowboy". Anyway, he was an outdoorsman and his tip was this..."vegtable oil'. He said rubbing it into the leather was important but even moreso, use a small brush and work it into the seams. Over the years I've used the vegtable oil with nothing less than great results...supple leather and long life. He said something about tannick acids (maybe that vegtable oil had none? If you want to expound on that, feel free). Anyway, this VX is the nicest car I've ever had and I was reluctant to use the oil on the leather, fearing that maybe I would screw it up. But, after mulling it over for 2 months...I did it 2 days ago. If you do it, wipe it on with a small cloth (I didn't use the tooth brush on the seams) and then remove excess. it looked pretty glossy for the first day, but then soaked in and now looks great. I also did the steering wheel and no, the car does not smell like a salad. You may want to try a small area first or maybe a baseball mitt. It works for me.
