Did some major 'vert shopping the past 6-years. I've owned 3.
'92 240SX
'95 Cutlass
'08 Saab 9-3 Aero
Current gen Sebring is fantastic - 2008+ models. The ones you are looking at are most likely rental fleet cars. Don't buy a former rental car.
We need room, a decent trunk and comfortable back seat for 2 tweens. If you need a trunk than remove all hard top convertibles from your criteria. With the trunk down they suck up all but about 4cu-ft of space.
The Sebring can be had in either soft-top or retractable hard top. With the soft top down, the trunk is still pretty damn big!
if you can afford it, swing up to a Sebring Limited - 3.5L V6 250HP and 6spd Automatic. The 2.7L V6 with 190HP is OK, but 4spd Auto.
The rear seat room is pretty nice - only better leg room is the Toyota Solara.
The downside to the Solara is it is a hack job 'vert and was not designed as a convertible. The factory builds a coupe and then send it to another facotry where they cut the roof off and mount a convertible top along with welding in plenty of support. Strucutural integirty is compromised and you end up with a wet noodle of suspension and torsional rigidity with plenty of cowl shake. Solara soft-top also does not stow away under a hard cover so its not as sleek or pretty to look at with the top down
The upside to the Solara is big trunk and lots of rear leg room plus a gorgeous interior. In 2008 they made some big improvements by adding HID's and an optional sport kit. The Solara coupe was killed off in 2009 and only Solara verts are made now.
EOS - tiny back-seat
CLK - tiny back seat
G6 - no trunk but decent rear seat. Same platform as Saab 9-3
BMW 3 - tiny rear seat (we only looked athe previous gen as we were not interested in hard top verts)
PT Crusier - tiny trunk and funky styling - Positive - turbo power in GT
Mustang - leg-room is pretty poor but decent trunk and cheap. The 4.0L V6 is plenty of power
Saab 9-3 - Turbo power, decent fule economy, luxury features everywhere, excellent warrnaty, free service for 3yrs, I own a '06 Sedan so am familair with them
C70 - boulevard cruiser, not very sporting
A4 - really liked these but resale was high
Came down to 4-cars for us. A4, 9-3, Solara, Sebring
We liked the Sebring a lot but the Saab won out because of the deal we got. A4 was great but resale value was high and finding one with the 3.2L engine was not the easiest.
Caranddriver.com reviews the Sebring, V6 Mustang, and Pontiac G6
They tested the 190HP V6
Chrysler has done a few cars right (Caravan) and the Sebring 'vert has been a very good seller for them. They made a very good, useful, convertible which some of us want.
The driving dynamics were important to us but we also needed functionality.
