Yes, I drove both, with little time frame between them. I suppose my statement is mostly based on reputation, from people more learned than myself. On the street, I didn't think there wasn't really much in between them - without absolutely spanking them, anyway. Under full power, they certainly sound different. The XR6T felt like it had a little more oomph from the get-go, but once the tacho started to spin around, the XR8 felt like it may have had the edge (at least, it felt like it was building up more power, the XR6T just felt powerful across the board - quite the opposite from the usual story of turbo vs. V8). This was mostly based on going up and down the freeway, full throttle on the entry/exit ramps. I certainly didn't give either a hard time through the corners, so the handling felt quite the same to me. Well, maybe the XR8 felt a little more prone to understeer (something I was very used to in my Subaru), but I may have been imagining things. The view out the front is completely diffferent - out of the XR6T, I saw nothing but road. In the XR8, that bulge was surprisingly (almost alarmingly) visible out through the windscreen. I also took a Late model camira SS for a test drive, to throw a spanner into the mix. It's a nice car, too - but the Falcon interior won me over in the end. The Late model camira felt like it had a more direct connection to the road, but it was also a bit rougher - sportier, some may say, but to me it felt a little less refined. The SS had more legroom and headroom than the XR6T/XR8, and the leather seats were the most comfortable seats I have ever sat in. But besides this, the car itself felt a little less refined than the Falcons, and the 5.7L was just a *tad* underpowered at low revs (IMHO). I would have been very happy with this car, but I was spoilt with the Falcons and I went back to them in the end. The XR8 was at a price I couldn't resist. That sealed the decision for me Edit: While I was purchasing the XR8, I heard from an FPV representative, who claimed the Mk2 XR6T w/ 6-speed manual is AMAZINGLY FAST - an improvement over the Mk1. This was almost enough for me to change my mind - almost!
