I've been keeping an eye on your transmission thread. I've got a 2007 with almost 130,000 kms (80,000 miles). So far so good. I mean I did have to deal with the suspension (blown struts, shocks, end links & worn sway bar bushings). And from being around this forum for a few years now... anecdotaly... I would say the only major (over $1000 job) issue that, scarily, seems to be coming up is the transmission. But looks like you're on your way to sorting that out now.
With this car, it seems to me that once you've upgraded the suspension with even basic aftermarket parts (not OEM), sorted the tire eating issue (which the previous owner must have done on mine as I haven't had to deal with it) you're pretty much good to go. Of course people have little problems here and there, switches, dash/switch lights, the odd sensor, etc, etc... things that fail on any car as it ages based on use and abuse (I've got a seat heater switch light that needs replacing right now!).
Again, the only thing that scares me a bit is the transmission. Mine seems to be just fine... but it does seem to be an issue that is cropping up more and more on these forums as the cars age and gain more miles. A fix for that might be (we'll see over time) replacing the trans fluid at least once a year or every 20,000 kms (12500 miles). I think this tranny, once past about 50,000 kms (30,000 miles), needs yearly maintenance to remain reliable over the long term... we'll see how that plays out over the next few years. I was in an accident a couple years ago, not my fault, but cost my insurance company about $8000, it wasn't even serious, parts, labour and paint are just so expensive these days... it was very close to being written off... needless to say, I'll be driving this thing into the ground as my re-sale value is probably s*** (how much would you pay for a 2007 with 80,000 miles, 2 owners, that's been in an 8k accident?).
I think the dealerships need to adjust the service intervals for the transmission and start telling owners to have the fluid replaced every year... but I guess that would amount to admitting it might be a bit weak for the 5, so we shouldn't expect that to happen anytime soon

.
Someone should start a poll asking questions about year, tranny issues, how often you replace your tranny fluid, general feeling about your tranny, etc.
(FYI, this is in regards to the auto tranny, just in case.)
