For me I'd say yes. Because most of my miles are done on the motorway the Clio was a bit tiring. The Clio handled more go kart like - the CTR does understeer a bit compared to the Cup, but hopefully sorted by the geo setup with adjustable camber arms (£295). VTEC is hugely addictive which sees my petrol needle drop quicker than Michael Barrymore's underpants at a pool party. So much comfier. No faster than my 172 Cup but the way the VTEC kicks in makes up for it. Easier to get more power out of it though.
Not a proper 'upgrade' as such, but definitely a better car in terms of everyday for non B roads. Parts aren't as readily available on the forum either but no big deal.
Oh and just for you, after owning ph1's and a ph2 Cup - for everyday driving (I've never tracked my cars), the ph1 is a much better built car than a ph2 in my experience. If/when I come back to 1*2s then it's a ph1 100%.
