It hasn't been a good week for supercar owners with reports from Perth and Switzerland proving it's not always sunshine and roses for the automotive elite.

Perth doctor Patrick Nugawela has had his 2006 Lamborghini Gallardo impounded by the West Australian police after his mechanic was caught speeding in the Italian supercar. The 53-year-old mechanic was nabbed doing over 160km/h in a 90km/h zone and under local anti-hoon laws the cops are able to lock the car up for 28 days.

It's the second Italian supercar incarcerated by the WA police after Australian Financial Review journalist, Rod Easdown, was pinged at over 200km/h last year driving a Ferrari California.

Understandably, the doctor is not pleased with the police's decision, likening it to being convicted of a crime he didn't commit.

"If that person (the driver) gets exonerated, I don't have the benefit of that," Nugawela reportedly told ABC radio.

"I have basically been subjected to mandatory sentencing without trial."

He has already had an appeal for the return of the car but it has been rejected by the local authorities.

"We try to be fair, without favours, so whether it's a Lamborghini or whether its a Kingswood or a Holden Commodore, we judge it fair, case by case,"  said WA police Assistant Commissioner for Judicial Services, Wayne Gregson.

Meanwhile, in Switzerland the authorities have handed down the largest ever speeding fine to a Ferrari driver of $315,000. The Swiss millionaire was busted doing over 130km/h in an 80km/h zone and it was the latest in a number of similar offences.

The heavy fine is thanks to the country's recently introduced road laws that fine people based on their financial wealth.
