I drove and towed with a 2.0 diesel 3008 for five years until last year. It was a good car in terms of reliability, economy, interior space and engine power. It towed my 1350kg and 1500kg caravans comfortably, with plenty of power in reserve, but the 2 wheel drive on the front lacked traction and the wheels would spin on gravel from standing (the outfit was in line and the caravan loaded correctly). The two cars are completely different. As a towcar the Antara is better by far in terms of stability and weight balance, but the Peugeot had better gearing - with both cars being manual - for overtaking. I find 6th on the Antara to be nothing more than overdrive and only good for downhill cruising, with 5th OK and 4th at 2000 revs the best.
