We drooled all over the E28 535i, but now we're in pain. Behold this pristine example of a 1988 E28 BMW M5, up for sale by Autohaus for US $18,987 - that would be �13.338 at today's exchange rates.

In Europe, the E28 BMW M5 was launched in 1985 and was equipped with a 3.5-liter 24-valve 6-cylinder engine with six separate throttle butterflies,delivering 286 hp and 251 lb-ft (340Nm) of torque. However, this here example is a U.S.-spec model, meaning it comes with the less powerful S38B35 straight-six due to stricter emission regulations. It was rated at 256HP and 243 lb-ft (330 Nm).

At the 26th Annual Brazilian Motor Show in Sao Paulo, the local motoring press were abuzz over Rossin-Bertin's Vorax. Carscoop reported on the carbon fibre bodied, BMW M5 engined supercar in an article last week.

We have videos aplenty, including a first taste of the Vorax's sonorous V10 soundtrack and a look behind the design process that features an interview with designer Fharys Rossin himself (albeit in Portuguese).

Remember Murray Fowler and his BMW 2800 CS? Then you probably wondered who the next impromptu actor in BMW's "Unscripted" series would be. Well, your wait is over: it's none other than female racer and television personality Sabine Schmitz, also known as the "Queen of the N�rburgring" or the "fastest taxi driver in the world".

She earned these nicknames for lapping the German race track more than 20,000 times (according to her own estimates), mostly behind the wheel of the famous BMW M5 Ring Taxi. Other highlights of her carrier include two wins (in 1996 and 1997) and a third place finish (2008) at the 24 Hours N�rburgring.

Behold Brazil's newest supercar, the Rossin-Bertin Vorax that will make its debut at the Sao Paulo Auto Show later this month. Looking a tad like the result of an unfortunate accident between a Nissan Juke and a Mazda RX-8, the Vorax features a carbon fibre body and aluminium chassis. According to its makers, it will weigh in at just 1,300 kg (2,866 lbs) and be powered by the same (albeit tuned) 5.0-liter V10 from the BMW M5.
