Hey mate the above car looks reasonable for that price but I think you should consider getting one with the things you already want on it. Exhaust, pod, coilovers are quite common and to find a car that already has those mods is only going to cost you roughly around an extra 2k anyways. Now factor in the price of say a good set of coilovers you looking at about 2k for that plus the other things you want to do to the car. So buying one with those mods is going to save you money that your trying to save now. Also I hope you have factored in insurance (approx $1500 for full comp) and rego $600 (if buying privately) and a full service up to $500. I'm sure a lot of guys on here would also agree on having at least an extra 2k in the bank for any unexpected problems. After purchasing my gtt with 68k on the clock my coilpacks went after about 3 weeks of ownership, so that was around $800 for a set of new spitfires. Remember your buying a car thats 10 years old and whether it has low kays things still wear out over time and need changing.
Good luck with your purchase.
