Ok, to make things a little easier can we have some answers?
1 - what will the car be used for, toy/24-7/family transport etc? Usage
2 - how old are you? Insurance
3 - is 13k the most you want to spend, or would 10-13k work better?
I only ask you these questions so I can make a decent guess at what I would want

But for that money right now, well I'd spend upto 10K on finding the BEST DC2 Integra Type R I could find.

But of the cars mentioned above, and the ones i've owned and driven i would say...... all IMO of course

CTR (o)- load of tosh! I got rid of mine after 4 months of irritation

Leon (d)- have never really been impressed by them, the Octavia VRS (o) made more sense to me and was pretty decent.
TT (d)-

I drove both the 225 and 248 V6, no thanks

Clio 182 Cup (d) and nearly (o) - now that makes sense but don't expect rock solid build

Mini cooper S (d lots)- Great motor with works kit a little flat without it, although i think the normal cooper (d) makes better value for money sense if you can't afford a works.
Mk5 (o) - it won't be long before they drop to your price, how about waiting?
what about some old school fun? a minter 205 1.9 Gti will cost you 3K or a decent Golf?
I might be getting rid of my Boxster S to save some money, as I've taken a new job with better hours but less money and have a short list if I were... Number one being a 106 gti, great fun of little wedge
