I've had a CTR and now a 172. Loved the CTR and definately faster than my 172. Also comfier, far better gearchange and less faults. But, the 172 has more toys as standard (xenons, cruise, traction etc) and far better steering, also arguably more fun handling. The CTR was grippy and planted but very hard to get the back end out without a dab of handbreak and pretty poor in the wet (on bridgestones). Brakes are about the same but you notice the clio is lighter. I just find its one of the most uncomfotable cars i've owned, a poor drivintg position lets down an otherwise excellent car.
However, given that you can get a far better condition, lower mileage 182 for that money, i'd go with it.
Alternatively, have you looked at bmw 330ci? A different drive but smooth comfy and fast. My dad had one for years. Faster than my 172 but only in a straight line!
I wouldn't buy any jap turbo nutter unless it was 2002 or newer! Older ones are so dated and common!
