Absolutely nothing.
Hard ride due to the leaf spring suspension on this model. Gearbox a bit 'agricultural'. However, had this car for 10 years & covered 150k miles faultlessly. Has never failed an MOT - particulate / emissions test still v good. Excellent for towing, go anywhere vehicle.
I have had my 1989 Rocky 2.8 Diesel for nearly 5 years now. I would rate the comfort as 8/10, Value for money 10/10, Performance 10/10, offroad ability 10/10, and fuel comsumption 10/10. You don't get much better then 6.2 Litres of diesel per 100 Miles.
You review is good, Great to see many Rocky owners out there. I also have a 1966 Model Series 2a Land Rover.
