Clio is a better handling car IMO. I wouldnt say a car that, as ozzie puts it, understeers constantly when pushed is a particularly good handling characteristic. It might be predictable, but thats not fun. Simple fact is it lacks the outright chuckability, agility and feedback levels of the clio and in my book this makes the clio a far more accomplished handler; cornering speeds are pretty much irelevant - plenty of cars can corner quickly but that doesnt mean to say they "handle".
Personally the CTR leaves me cold. It looks ok, i suppose, but it feels like your sitting in a people carrier when you drive it, the chassis lacks fun factor, the steering is rubbish, it feels heavy. As for the engine, it disguises its lack of torque by having ridiculously short gearing. Its good fun to push hard, but it doesnt feel all that quick, and the engine note was disappointing to me, it just sounds strained and thrashy. I wouldnt have said it sounded any better than the Clio TBH. And it feels slower, even if it isnt. Add to that, the fact it costs more to buy and run and comes with less standard equipment, and for me, it was never a particularly enticing option.
The LCR is basically just a Golf Mk4. Its the best handling out of the VAG platform cars, but the engine has a dull sound, and it feels heavy to drive. Its more of a grand tourer than a thrashy B road blaster, of course you may like that. Definitely more effortless to drive either, but that could be boring if you enjoy having to work for your thrills. I'd say it was the best looking car of the lot though.
