As they say noting ventured nothing gained. Age of car , and yourself should not pose any problem. If you have not got an MOT might be worth getting one or at least make sure your insurance company is aware there is no MOT. Take what spares you can so they are available if you do breakdown even though you might not be fitting them. At least in France your much more likely to come across a breakdown engineer who has actually seen a traction before.
