Discovered my car has a hidden accident history - what should I do?

I purchased a Lexus GS 450h from a main dealer about three years ago. The wings are now going rusty and Lexus have said this is due to inconsistent paint thickness from a previous repair and is not covered...

The garage have found a fault with a car I traded in - what are my rights?

I signed and drove an Audi away from a dealer on Friday. The garage now want me to go back as they have found a fault with the trade-in car. What are my rights? My car was bought as seen.

Banned from driving, is my car insurance still valid?

I have been banned from driving for several months. My insurance policy has my wife registered as a secondary driver, can she drive the vehicle without having to change or inform the insurance company?

Lexus GS (2005 - 2012)

Very refined and quiet. Effortless performance from all engines. Hybrid GS450h is superbly refined. Stuffed with technology and equipment. Excellent crash test rating.
