hey lexions (lame) I'm from Sydney Australia currently looking for used lexus is250. Wouldn't call myself a car enthusiast, I more or less love the aesthetics of certain cars, the lexus is250 being one of my fav. I will be looking to purchase a lexus soon, any advice in terms of price range, upgrades, maintanance costs would be highly sought after. Cheers p.s. looking to get 20 inch wheels and awesome sound system for my car !
