I've got a 115, road tax ?125 a year, ins about ?280, my one goes well. Dont think you get as many problems with the L series derv engine, as you do with the K series.
Had it for two and a half years and touch wood, no serious problems, apart from rusty rear sliders on the o/s/r, which needed new disks and pads to sort out.
Best bet, would be to go out for a drive in both cars and see what you like. Its a different way of driving the derv, as they pull all the way through the rev range. With a petrol engine its all revs to get the speed.
Hope you find something you will enjoy.
