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.

2015 BMW M4 Convertible debuts: drop-top fun priced from $73,425

The 2015 BMW M4 Convertible made its official debut at the New York auto show yesterday. While the details of the high-octane hardtop didn't exactly catch us off-guard (see our full breakdown here), we now know how much it'll cost to feel the wind in your hair as you launch from 0-60 mph in 4.4 seconds: $73,425, to start. Complete pricing will be available closer to the M4 Convertible's sale date, which is “late summer” 2014, according to BMW.
