I'm really concerned about what will happen when our cars approach 30, and 40 years old. The muscle car era benefits from heavy vinyl and metal, and any plastic'ish bits are also heavy and thick, plus there are so many aftermarket suppliers to replace almost anything you could think of on a 68 mustang, a 69 charger, or a 69 camaro.
I don't trust that there will be much out there in 2045 to replace parts on an 05' SRT-4
I'm very thankful that the plastic (especially engine bits like hoses and connectors) is miles ahead of the late 80's early 90's cars. Vacuum hoses on those things just disintegrated after about 8-10 years.
Last year I was trying to get a part out for a buddy off of an old shadow we had, it even sat in the shade at our farm for the last 20 years, albeit outside, and the electronic plug in broke into minuscule pieces when I tried to push on it to separate it, this obviously under the dash, where you can't really blame UV light.
I just hold onto faith that the plastic in the SRT4 is a lot better, and somehow maintains... fingers crossed?
