SCHMOE, You must be kidding ! GM is king of the cheap plastic. THe dash in the Silerado's sounds like a hollow log and all the plastic in the cockpit is ultra cheap and brittle!
GM also has the most plastic laden claded vechiles I have ever seen. Look at the Avalanche, Azteck,Grand AM,Grand Prix the entire outer panels on all Saturns..... Plastic!!! THe interior of the SSR is Frankinsteinish!!! The plastic is cheap has visable overlaping seems, has sloted panel plugs the size of quarters that are plainly visable and the climate control knobs came off in my hands while driveing one! The knobs are suposed to look like brushed aluminum but you can tell they are coated plastic even before you touch them. The XLR's center counsol and center stack screamed cheap plastic!! THe Corvettes C5 were compared to Mattel Toy COmpany for their cheap plastic interior. The Cadilacs fake wood looks like fake plastic wood even before you touch it.
All companys use plastic as a primary material in the interior now but some feel cheaper and sound cheaper then others. You also see a huge difference from one model to another. I think though that any vechile costing more then $20,000 dollars should have multiple tectures, and color breaks, no overlaping seams, and you should not be able to easily spot fastners. It should sound solid resonate very little etc.
When the car cost more the $38,000 the wood should all be real. The plastic should look and feel like a paded leather dash and any bits that look like a polished alloy should be!
Their is no plastic clading on the outside of my Camry other then door dent guard with is color keyed and less then 1" in width. My Dads Tacoma has no plastic on the outside at all that is visable. My Moms Tundra only has Molded flexable urathan flares on the outside and they are very small and tastefull.
