Hi Ciaran . . good to speak to you last night, welcome to the club and forum.
For £10-11K you're not going to find a solid S (if you do, please let me know [
]) . . so an early 2lt, T or E is the way to go, remembering that it all comes down to condition. Nick's source could be worth a look.
Below I've detailed some useful websites . . . the first two should help you decide what car you're actually after . . T,E,S / Coupe or Targa etc. The rest will have cars for sale (hopefully). Buying from a dealer isn't obviously going to be the cheapest way . . so keep an eye on the classified ads . . . Targa's will be cheaper but are becoming more desirable IMHO . . . left hookers will also be cheaper (mine's LHD and I've no problems drivving it . . but every LHD owner would say that wouldn't they).
