Can I ask some questions?
Stereo is absolutely fine, it's nothing fancy but I don't have a problem with it at all. Sounds better than anything I've had in the past (although that would only be a Clio, Peugeot 306 and Citroen C5 with stock setups).
Engine is good, better than I remembered from my test drive. I do a lot of long journeys so I tend to sit in the inside lane cruising at 70. However, the engine is certainly spritely enough for me to let rip on the A roads for some fun.
Haven't tried the Nav yet. The documentation is huge, I've got to spend some time going through it. I've never had a sat nav before so I'm used to map-reading and memorising my routes
No special number I've noted.
I drove in the dark for the first time the other day. I was aware of some comments about the headlights however they were absolutely fine for me, nice and bright and importantly were at the right level (not aiming too low from what I found).
Very pleased so far. No creeks or rattles (touch wood) and everything works nicely.
EDIT - I pulled into a service station at Chievely the other day. I had one chap walk in front of the car whilst I was letting the engine idle for a bit and his jaw dropped and he actually omitted a "phoooar" sound. It turns lots of heads. Absolutely beautiful car.
