I just received confirmation that it sold for £15'500, not too bad, and its pleasing to see car sold rather quickly compared to cars that I see on Autotrader 🙂
Just seen video, 100% true, I think would have had a better chance maybe with the GT63s V8 hybrid. That one has 1400NM of torque with the help of electric motor. Surprisingly, Audi took the lead, I thought BMW should have come first. 🙂
I haven't watched this video, but my prediction, is as much as i like and suppport W213 E63, it will be last again. Have seen a few various videos, e63 seems to come last but it's good at rolling race though.
Watching video now, I could be wrong 🙂
