I’ll admit to quite a collection of Rover, British Leyland and BMC brochures.

I even own a few of the cars illustrated in them, but my hoarding is nothing compared to the major classic car collections that will be going under the hammer in the next couple of months. 

First up is a cache of 200 Porsches, collected by an anonymous man in the Midlands who’s thinning out his collection. Which, if this is a thinning, must be enormous. The location of the cars that will remain with him is a secret, incidentally. The subjects of this cull are to be sold by Anglia Car Auctions at a series of sales over the next few months, the first of them on 24 August. 

The collection includes 50 early 911s, 39 of the smaller-engined four cylinder 912s and 40 356s, among other Porsches. Conditions vary from cars needing bumper-to-bumper restorations to examples that are pretty much ready to go, and if you fancy an early 911, 912 or 356, there’ll be no better chance to size up a choice this big.

At much the same time as these Porsches find new owners, another collection of no less than 500 cars, most of them Chevrolets from the ’50s, through to the ’80s, is being sold in the US. What’s special about this vast array of American iron (and glassfibre – there are a few Corvettes in the collection) is that they all come from a former Chevy dealer in Pierce, Nebraska.
