Had the Legacy for five weeks now, so thought I'd post some developed impressions.
It really is a great car.
The ride and handling has taken a bit of getting used to after the Forester. The handling is way superior - it corners like my modded TT used to. So flat and sharp. I haven't found the limit yet, I can't quite imagine where that might be, TBH. The ride is much stiffer: speed bumps are ok, if you're sensible - I never used to slow for them at all in the Fozzer but you really need to now. However, there are a few level crossings near me and they are horrendous
The engine, though, is just great. You can be really civilised if you want. Stick it in Eco mood and just pootle around (eco mode really kills any throttle response).
However, put sport# mode on, get past 3k revs, and it's a strawberry floating animal. It's crazy really, because you just run out of road really, really quickly. It's actually turned me into a slower driver, which is a good thing, because if I put my foot down even slightly, I'm just braking again in a few seconds' time. So it's easier just to chill.
Oh, and the car gets more compliments than I was expecting. It's completely stealth/debadged, but I've had two people ask if it was a Spec B, then nod approvingly, and a further two people properly craning their necks as I went past. It's not loud or anything (does have a tiny bit of BPV pshhht noise).
