Good luck on the search, I hope you find a nice one. I've yet to ride or drive in a GS, but I think I may trade up for one eventually.
First off, I did make it to the premiere for the GranTurismo last night, I took some pictures and will post them in the general section in a bit.
What is the Aston ride and drive? I haven't made it up to LFSC yet, but may be visiting a buddy in Highland Park this weekend, so I could check it out.
As far as the maintenance goes, I can't really complain at all at this point, no real mechanical issues. I have had my '02 Coupe for a year now and it's been pretty much my daily driver. I have it serviced at Continental, though I will probably start doing the basic stuff on my own now. I'll have to dig up the bills from Continental. The 18K was done at about 16K miles just before I bought the car, so I don't know what that would run. I think my last 6K service was around $1000. I have the original clutch, but the F1 pump was supposedly replaced with the 18K service. Again, not sure what they would have charged for that.
I would love to compare my sound to a Tubi coupe or gransport, but I have not come across someone else around here to really compare. They have started up a Tubi coupe for me at Continental, but not much more than that. Keep in mind there are three versions of Tubi, with an increasing level of loudness. I guess all I can say it that it's really subjective. I have heard nothing but raves about my exhaust note, but I'm not sure if I'm 100% happy with it at this point.
