I understand a Vectra fastback swallows a full bike, as pretty much all fastback type cars will do. However the CombiCoupe was launched as a result of SAAB typical out of the box thinking in a time pretty much every car manufacturer carried a saloon and only a saloon in that class. The CC can't be considered the very 1st though as I would think that honour goes to the Renault 16.
From '02 on the fastback model completely disappeared from the SAAB line up, giving up an untill than unique selling point and proofing there was no room anymore for a sincere vision on function. A saloon is pretty useless or at least highly impractical when you want to transport bicycles regularly, so an estate would be the only alternative. I prefer fastbacks over estates though, because of the large entry, for estates they ask a premium and personally I tend to like the looks of the fastback more.
I would have absolutely no idea what I had to buy if I had to buy a new car. A Land Rover is like a Swiss army knife to me, but I am not so often off road. Another clever car is a Lotus. Of all other cars I simply do not see the joy of owning. They are mere disposibles for me. Uninteresting, non sincere and absolutely not worth preserving. That is not how a want to enjoy and use my cars. Better keeping my current and buy myself a Lotus as 2nd within a couple of years.
