Vintage photos show Ford Mustang I and the elusive XD Cobra

It's hardly surprising that our readers want to share their memories of the Ford Mustang -- 50 years is a long time for an automotive nameplate to endure, and the model's upcoming 50th anniversary is as good excuse as any to look back on the experiences that have made the car an enthusiast hit. Take William Drew, who had a close encounter with pony car history when he saw the Mustang I concept, plus a rare Ghia-bodied Shelby Cobra concept, at an auto dealer in Dallas in 1970. His slides (taken with a Yashica camera, he notes) show the unusual cars in the nice, bright colors of Kodachrome.

Mercedes GLA Concept: OFFICIAL

Aimed at cars like the BMW X1 and Audi Q3, the GLA is a good-looking compact SUV that carries much of what’s good about the new A-Class, raises its ride height, adds a few butch bits and creates a car that will probably have more appeal for owners of the old A-Class than the new A-Class does. The GLA heading for the Shanghai Motor Show sports a 2.0 litre turbo with 208bp, 4MATIC and a 7G-DCT gearbox – which we guess makes it a GLA 250 – and sports something new – laser headlights that function as projectors. The GLA features a pair of cameras on the front of the roof rails that can take 3D HD images and can be removed if you want to use them for mountain biking or jet-skiing or whatever floats your sporty boat.
