I try to use a local tire shop but I bring TireRack information with me when I talk to them. Sometimes the local guys can make the price worth using them totally and sometimes they tell me to buy from TireRack. Either way, the local shop gets the installation.
I have used Michelin PS A/S ZP's (run-flat) on my 2003 and I thought they were great. I have not tried the non-run-flat version of them but I would think they would be even better.
I have used Goodyear F1 D3's on my C4 and was very, very happy with them. I have F1 D3 EMT's on my CTS-V and I'm very, very happy with them.
However, I think you will like the Michelin A/S tires.
