Convertibles are my favorite, then the coupe. I like the fastbacks alright, but they're definitely #3 on the list.
We've had several discussions on Mustangs over the year but you might not recall, my dream car is a 1965 Mustang convertible 289. 66 would do, as well. As you mention, 67 on up had differences in styling that are less appealing IMO-- particularly, the bodies got a little bigger and wider and just clunkier looking and although I still like them and would happily drive one, it's not my dream car.
Yes, I remember your dream car being a '65 Mustang convertible. Did you have a favorite color?
The fact that you like the coupe better than the fastback ("2+2") seems consistent with your dislike of the styling of Volvo C30 and, by extension, station wagons in general.
Remember the 1st-generation Ford Taurus? It was a big breakthrough for Ford in the way that the K-Cars were for Chrysler a decade or so earlier. The hot version was the SHO.
There was a sort of cottage industry of converting 1st-gen Taurus wagons and/or SHO sedans into "SHO Wagons."
Like this. Which you would not like.
Car and Driver tested a conversion and gave it rave reviews.
I guess you would not be a fan of this sporty Volvo 1800E.

I had a fraternity brother who had a similar car. I thought it was pretty cool. OTOH, I thought that the similarly proprtioned (albeit smaller) MGB-GT was ugly. Sometimes, there's just no accounting for taste.
