Just my $0.02 worth but as a cranky old man maybe that's okay anyway?
Everytime another of these "generation" threads or questions arise it seems to become a bit of a mess since there are significant differences in the years affected. Trying to lump 16 years of any vehicle under continuing production seems at best a crap shoot.
To me--and maybe only me---specifying the year and chassis along with fuel type tends to be most helpful. Saying "I have a 3rd generation whoosiewhatzit." tends to raise the question year, make, model, chassis and fuel type anyway.
It might seem useful to some and it very well could be---perhaps I'm just too anal?
