So I am looking to sell my 1993 Corvette 40th Anniversary coupe and get into a Crossife of some sort. The vet has just been too much of a money drain and with one problem after another, I am scared of what may be next. I have found a couple Limited COnvertibles near me ($20,000ish with about 10,000mi) and one SRT-6 coupe (just under 10,000mi for $21,000).
My dream would be an SRT-6 Convertible, but I think right now it is just too out of my price range.
Anyway, I would like to hear some feedback on which XFire would be a better choice for me. I liked the open top of the vet, which the convertible would have, but also liked the performance which the SRT would have.
I am 28 years old and live in Iowa. This would be a 2nd car for me, so I know that it does not need to be good in the snow or poor weather.
So, Convertible vs. SRT:
Does one have more expenses than the other?
Is one more reliable?
Are there more common problems with one than the other?
Will I like the openness of the convertible more, or the performance of the SRT more?
Anything I am not factoring in?

Any input would be great. Thanks!
