I thought the A45 was a fantastic car to drive, but it feels like a rally car (due to the seats to a large degree), where as the Golf R just felt like a normal Golf that went very fast if required. The latter therefore being better as a more subtle and pleasant daily driver. The A45 is a pretty serious performance car, the brakes are among the best I've ever used too.
To a lesser extent that's the appeal of the Polo I leased. Through choice I wanted something cheap as I have been guilty of spec creep on these things in the past so set myself a budget of circa 150 a month to stop that. I would have been annoyed if I ended up buying something for 30K after said spec creep! I also wanted something that could be fun but most of the time was just a good little car that would look after me, be easy on me and could park anywhere.
