Shh about the CX7! I’m lining one of them up for when my 9-5 Aero wagon has a few too many clunks and bangs, and people don#’t seem to have cottoned on to them yet, let’s keep them a little secret 😀
C6 RS6 is my unicorn. That V10 is magnificent, the initial purchase costs are OK, but the running costs and risk are, to me, utterly terrifying. Their ability to empty a bank account seems only comparable to their appetite for fuel. A truly intimidating ownership prospect. But my god would it be worth it. Easily tweaked to very impressive figures for comparatively little.
The C5 holds a big attraction as well, and perhaps an (only marginally) less expensive proposition, but that’s more do do with original purchase price, the running costs are still pretty intimidating.
Legacies ar the more cut price option that’s pretty appealing as well. At the bottom end, my 9-5 is OK, but it’s very much a one trick pony. Not tooo bad on fuel, solid and reliable, enormous inside, (L 650b enduro bike fits with the seats down and both wheels on.) but it is essentially a Vectra with a few Saab bits (like the engine). The Saab bits are really the only vaguely interesting bits about it. Very hard on suspension components though. I seem to be forever replacing bushes.
