IF ever there was an obvious wealth indicator it has to be luxury sports cars. While The Note doesn’t have the power to do number plate checks, our operatives have observed how many of these bright, shiny machines are on the roads these days…or more likely parked by the coffee shops on Bay View Terrace, Claremont. And if you are doing it tough, it seems it’s likely your penchant will be an Alfa Romeo, closely followed by a Porsche, both of which have both sold around 35 per cent more vehicles in Western Australia so far in 2007. A fair way behind them is a pack of rarer names. Ferrari has sold 18 vehicles, up 260 per cent, Aston Martin 17, up 70 per cent, and Maserati 16, up 14 per cent. Lotus has recorded the best growth among this lot, at 900 per cent, to 10 cars. Just to round things off, Lamborghini has sold eight cars, up 167 per cent.
