Perhaps I'm lucky, but also I made sure the QPV's I was serious about I had inspected at my expense... and finding out about the subframe (or other issues) before I parted with my hard earned cash.
After flirting with 3x facelift ('08 onwards) QPV GT S's and paying for two inspections, I settled on the 4th... here's a breakdown of my costs of ownership, one year in:

I personally wouldn't go near a V8 powered BMW (with the exception of the M5 E39) and expect it to be synonymous with German reliability... that's reserved for their straight 6's, in my experience, and the amount of tech in the newer 7's surely means something will give eventually. The CL was a barge I also considered for wafting away the miles... biturbo 4.7 'bluefficiency' (LOL) was a screamer, but lacked the excitement of an Italian.
The Quadrifoglio Giuila is more modern, faster... but I don't think quite as pretty as a QPV GT S (and I like to remind them of this by driving past with the exhaust valves bypassed at full chat
). If you're considering a QPV, I'm with
@Twinspark - the facelifts are better looking (2008 - 2012), and you can't go wrong with the 4.7 (so long as it's a post-varistor fix car... I think the cutover was 2009-ish).
