VW Golf GTI priced from £25,845 in UK

The new Mk7 VW Golf GTI is now on sale in the UK priced from £25,845. That's only a £195 rise over the old Mk6 Golf GTI, despite the extra power, performance, and a 2.2mpg improvement in economy. Hang on - nearly £26k for a VW Golf GTI is a bit steep, isn't it?  Actually, it's better value than the old Mk6 Golf GTI. For a start, the new Mk7 Golf GTI's 29E insurance group rating is five groups lower than the old model's, so you should save on premium renewals as well as road tax and fuel fill-ups.

Concept Car of the Week: Peugeot Proxima (1986)

Presented at the 1986 Paris Motor Show, the Proxima concept was the ultimate vision of '80s futurism, both in terms of its design and engineering. To assert its blue-sky vision, Peugeot named its creation after Proxima Centauri, the closest star to the sun. The exterior design was directed by Gérard Welter, and featured a long wheelbase, mid-mounted engine and very small overhangs, putting the accent on power and performance.
