What should I look out for with a 197?

Hi all, I'm looking to change my Clio Williams for a 197. Iv seen a nice R27 but not sure if it justifys the extra cash, what do you guys think?:001_unsure:
 
I want something as fun to drive as the Williams. Just not as noisy and old! Lol
Iv got another car for weekends so not too worried about tuning it.

My understanding of the R27 is the fully loaded 197 with the cup pack ie, wheels, suspension, recaros ect but still has the aircon, keyless entry ect. Am I correct? Please advise if I'm off.
Cheers
 
Thanks for link Mike, been very helpfull. I just need to find the car now, the R27 I was going to look at iv just found out only has part service history and will be due for the cam belt change! He tells me this is why it's up for 5800, I'm just dubious of the part history and the fact that the cam belt is über expensive.
