Well I exaggerated a bit, my 1985 Volvo 240 is only 27 years but I plan on driving it until 2015. Mercs from the same era also used vinyl.
Please. The Mercs used "MB Text," not vinyl, LOL.
Get the leather. Much better with wet/damp clothes than fabric. Cloth would be my third choice after leather and vinyl.
My buddy has a Chevy Traverse, pretty nice car that bridges b/w minivan and SUV. That said, my wife's Odyssey is much more useful than my Tahoe
