Looking good.
When I test drove a brand new Monaro and a few 350's demo cars way back in 2003/2004, I found the Monaro a bit of a whale in comparison to the 350. Obviously the 350 is no size 0, but still reasonably agile. Only bonus with the Monaro is the V8.
Anyway doesn't matter, you're enjoying your Z. Take care until you're used to RWD especially with the current mix of tyres.
