The BMW 1 SERIES (2007-13) 135I 2DR CONVERTIBLE 3.0 306 EU5 M SPORT DCT AUTO7 is a compact premium two-door with a folding fabric roof, sitting between everyday small hatchbacks and larger, pricier luxury convertibles. Its M Sport styling gives it a purposeful look, while the 3.0-litre petrol engine and seven-speed automatic make this a notably powerful, open-air choice rather than a basic runabout. Mycarcheck.com records are based on 26 look-ups covering 19 different cars, so treat them as a useful snapshot, not a full market picture. Within that sample, the average recorded mileage is 67,000 miles and average annual use is 3,000 miles; cars average about four previous keepers. The average private-sale valuation is £4,700. It suits drivers seeking weekend fun and a distinctive alternative to Audi A3 or Volkswagen Golf convertibles. Limited rear-seat and boot space, plus higher running costs, are offset for enthusiasts by strong performance and roof-down appeal.
