Long Distance - Possible Problems

So I've decided that the RX8 I'm wanting to buy is going to be in another state as those over here haven't been maintained/drove correctly etc. The compression tests are terrible and there are quite a few interstate that Im interested in.



I'm just wondering, as I will fly there and drive back, what possible problems I may encounter. Assuming the worst possible outcome I will be travelling around 4300km's (around 2700 miles.)

As you can imagine, I'm not overly keen on breaking down interstate.



Thanks for future help!
