I see people refer to convertibles and roadsters or roadster convertible are they one in the same or are they different

 

Same
Technically a Roadster is a 2 seat car
Convertible is a 4 seat car

 

So what i so what I want is a crossfire roadster convertible is that what I'm looking for

 

Yes - roadster.
BTW, SRT6 = supercharged, about 330 HP untuned
NA = Normally Aspirated, about 215 HP untuned.
All are 3.2 liter V6

 

All Crossfires are two seater cars therefore all Crossfires are called roadsters if the top goes down

 

You want a Crossfire roadster.

 

Technicqally a roadster like the Crossfire has a disappearing top and may have wind up windows. If the top is visible or under a fabric cover, it is a drop-head. Both are convertibles. And then there are retractables.

 

Tell us about retractables, please, Padgett.

 

Sure: Ford Sunliner, XLR Cadillac, SLK Mercedes, Pontiac G6, BMW Z4 to name a few.

 

Oh, I should have known that; I have one! It's a 2008 Chrysler Sebring. Not many were made, and this model was discontinued as an economy measure during the 2008 economic crisis.
It's not a roadster, technically, because it has a rear seat, which no one has ever sat in, because it has about 4 inches of leg room.

 

Mercedes refers to convertibles with two seats as roadsters and four seaters as cabriolets.

 

OK terminology is like a holy war to some but in order of complexity you have


Speedster - usually a 2 seater, erector set top if it has one, side curtains if present.


Roadster - may have a folding top but disappears under the tonneau usually a two seater


Drop Head Coupe (UK) aka Cabriolet (Eur) folding top that is visible or under a fabric cover when down. Can be two or four passenger


Convertible Coupe (US) single row of seats,


Convertible (US) may have multiple rows of seats


- all of the above have fabric roofs


Reatractible, Retracting-roof Hardtop , or Hardtop Convertible (US) -metal folding roof - 1957 Ford Sunliner was first production car. Modern ones do not have the FA.

 

Chrysler advertised it as a roadster, that is good enough for me.
