Now a rarely-seen collectors' item, the first E28 BMW M5 debuted at Amsterdam motor show in February 1984. Designed to combine the carrying capacity of a saloon with the performance of a sports car, it was based on the E28 535xi chassis and featured a bodykit evolved from the previous E12 M535i.
A simpler time for interiors!
At launch it was the fastest production saloon in the world, with a torquey 3,453cc straight-six producing 286hp at 6,500rpm. Top speed was quoted at 155mph, with the M5 claiming a 6.1-second 0-60mph time.
By modern standards this first M5 does looks pretty boxy and somewhat restrained, but the simple and airy E28 cabin is uncluttered, with just two large classy dashboard dials and simple, easy to understand switchgear. Like most cars from the 80s the driving position is pretty high, the seats feel basic and the steering wheel seems incredibly thin - especially when compared to modern BMWs.
Only 2,191 examples were built, making this one of the rarest BMW Motorsport models. On the road it drives like many classic saloons of that era, but with much sharper throttle responses and a harder-edged engine sound. Gearchanges can't be rushed and everything flows that bit more slowly, but the ride is beautifully cushioned. By 2017 standard body roll is significant and the brakes aren't the strongest, but the tail is easily controlled - albeit with plenty of steering input.

Just 189 cars were sold in the UK and values have rocketed over the last few years, especially for the very best examples. According to James Redish at M5 specialists Redish Motorsport: "Aside from a strong provenance the key issue buyers should look out for is rust and corrosion - the front wings at the bumper joint, inner front turrets, jacking points, sills and rear axle mounting area are all prime locations."
Aside from the tin worm, buyers should beware any timing chain issues, excessive play in the steering linkages and worn rear axle beam bushes. Prices start at £25,000 for cars needing TLC, with concours UK examples now fetching over £40,000.
