Geez, why do so many threads here devolve into such a mess?

OK, you asked a simple question............ so here's a simple answer:

External visual differences:
- Wheels: SRT models have multi spoke wheels that are vastly different from those shared by the Limited and Base models
- Rear spoiler: SRT models have a large fixed rear wing that replaces the automatic spoiler shared by Limited and Base models
- Front spoiler: SRT models have an integrated lower chin spoiler that the Limited and Base models lack
- Trim: Base models have gloss black trim where the Limited and SRT models have silver (windshield surround, side strakes, door handles, etc)

Interior visual differences:
- SRT models have suede/leather seating that is not available in Limited or Base trim
- Leather interiors of Limited models come in a variety of color combinations not available in either SRT or Base models (dark/light gray, vanilla/dark gray, cedar/dark gray)

That's really about it, or at least the most noticeable differences between models. Between model years, however, there really isn't much of anything different that would be an immediate giveaway (unless you can spot the automatic dimming rear view mirror in 2004 models from 100 feet away).

Of course there are all kinds of modifications people have done, from custom wheels to custom hoods to blacking out otherwise silver trim, etc.
