How do I say this with offending the host, but that place you mentioned not so great on prices.
TSXs are one of the most bullet proof used units on the market. Just with normal servicing 300k km is not a problem so even picking a unit with 140k km is not an issue. I just bought a 2004 auto, extremely clean, all records, winters, 1 owner, although I haven't received it yet, leather, loaded for $5500. wholesale with 140K km so 2LATE should be able to swing something in the range of 10K plus 1K in reconditioning.
When you think about it, the alternative is what was mentioned: civic et al, but that's TRANSPORTATION. If you want a gratifying manual shift experience in a sweet car riding with a motor that you will not touch I am really at a loss for under or around 12k.
