Local garage in Exmouth will do the belt at 1000 pounds. Of course, if the removed belt does have damaged teeth, there may be hidden problems. There would also be a need to change oil during belt replacement as the end plate of the engine has to come off
A lot of modern cars now require removal of the whole frontal area of the car including radiator and air con radiator etc.
My boy can often be seen working on a car with no front end fitted. I was doing an alternator on a Fiat 500 Abarth down there and the right side drive shaft has to be removed to do that.
For a challenge on a fairly modern car, try changing an indicator lamp on a 2007 Renault Megane. The only person who might get their hand through the hole under the car would be a woman. Men can do it but boy is it hard work. 2 hour job removing front wheel and wheel arches then take off covers behind the front bumper.
Cars are not anything like cars of 30 years ago. Now, if you change a battery, it has to be logged into a computer for the car to accept the battery. It took 30 minutes on my new Toyota just doing the programming.
The Ford 1 litre should be avoided unless its brand new and you are not going to keep it more than a few years.
A 1983 Ford Escort 1.3 can snap a belt and no damage, just fit a new belt. If you have a 1.6 Ford Escort, the valves hit the pistons and the engine is Donald ducked.
Get a Range Rover and find the belts are at the rear of the engine. A newish Jaguar V8 has bio-degradable intake manifolds and they degrade in 12 years and the intake manifold collapses. Maybe only on one side but a very expensive repair
