Koenigsegg Agera at Goodwood: Up close and personal

Koenigsegg Agera on the Goodwood hillclimb We have to confess that we have a huge soft spot for the creations of Christian von Koenigsegg. So when we knew that friend of Cars UK Tommy Wareham, purveyor of all things stunning on four wheels at SuperVettura, was taking the only Koenigsegg Agera in the UK to Goodwood we thought Claire’s Goodwood Odyssey should continue with a good poke round the Agera. Understandably, Tommy wasn’t going to let Claire – or anyone else – loose on the Agera up the hillclimb as it’s a customer’s car, but he did chuck Claire the keys for a good look round, the opportunity to grab a set of Agera photos (below), and the chance to dream… Beautifully finished and oozing carbon fibre from every pore, the Koenigsegg Agera is perhaps the ultimate bonkers supercar, at an equally bonkers price – just think of it as a million pound supercar; it’s close enough.

LX-rated love-in: Web forum members make their virtual passion real

The Dodge Charger, the Challenger and the Chrysler 300C share more than what Chrysler calls its LX platform. They also share an enthusiastic owner base at the www.lxforums.com Web site, where for the last six years more than 33,000 enthusiastic owners have met virtually to share information, photos and love for their cars. Event founder and 2005 300C owner John Fortuno calls it a "modern-day version of the car club." Five years ago he decided to "bring the virtual to reality" by staging a Spring Festival car show in Southern California where members could meet in person.
