I've had my RX300 for nearly a year now and coming upto 25K on the clock. Its a great car and would recommend it to anyone, its certainly no slouch and holds its own against most cars. Definitely a cruising vechicle rather than a 4x4, mine gets most of its action on the M4 and its a relaxing drive. You're right about the petrol though wont get more than 21 miles to the gallon, so wouldnt recommed it unless you have a fuel card or spare petrol tanker in tow.
Does anyone know what you have to do to get updates to your DVD sat nav's ? Is it possible to have the sat nav console support tv output ? I'm trying to find some people who could do this any ideas ?
