OP, sorry can you please be more specific?
You mention performance, and in the opening post talk about a TD, which is just a contradiction in terms.
Do you mean you'd like "moderate" performance, but in a car that looks nice?
If you do, you might want to consider cars like an Alfa 159. Now pretty cheap. Not a genuine "performance car", can be had with a decent diesel, looks ace from the outside and has a lovely interior that genuinely feels special.
If you're talking about something with geniune performance, do you mean "it's fast", or "it's fun and reasonably quick". Typically bigger heavier cars with big engines are genuinely fast, but often not that much fun (massive generalisation). Hence why a Swift is actually worth considering if you want fun, then maybe a CTR. You want something quick, maybe a 335i.
You really need to help us.
