the 370 is shorter and lighter than the 350, it is still heavier than you expect a two seater to be at ~1500kgs, but is similar ball park for many of those cars in your list, its 344hp is decent enough to propel it along but never feels rapid, just quick, reasonable value now though, loads of dealer demos around with a couple of k on for ~27k also cheap to tax the big engine these days at £140 now the rules changed for post Mar 2017 cars.
I suppose it's a different power delivery which isn't always a bad thing, I just find the golf too clinical, even my girlfriend prefers the feel of the Focus - they're fast don't get me wrong and a hoot on the right roads, just a bit numb sometimes. I've owned it for 6 months now so I tend to get an itch for a new car at this point, I need to stop scratching that it as the wallet doesn't like it!
I’ve owned my MK3 Focus RS since new, still love it. Regularly get people asking me about it too, which I thought would have stopped after 2 years! Whenever I walk up to it it puts a smile on my face.
I do love the look of these, did consider one for a short time but never got round to driving one yet. I feel it'd be more of an occasion than a lot of things.
