Hi SushiBoy,
Great choice with the Aurion, ive had Holden and Mitsubishi and must say the Aurion craps all over them in terms of ride and comfort and economy. Just make sure it has been well serviced by a reputable mechanic and that everything works, get in push buttons adjust everything and so on. I was offered a 3 year dealer extended warranty which virtually only covered drive train etc which I thought was great until I saw the finance guy who said he could do better and for $1500 i got 3 year full factory extended warranty.
Modded cars are ok if it is what you like or go for a standard one and plan your own mods ( there is heaps on this forum ) and as for color its really a personal choice, I personally like white but as I said its a personal thing so choose one that you are happy with.
Good luck with the shopping and hope to see some pics once you pick one out
Cheers
Peter
