The more equipment one has, the more time one spends looking after it all .
The longest time served vehicle I have is the SWB Land Rover, pre 1973, Nill Road Tax and low insurance. I very reliable, been around Scotland , Devon and to Kent. Love it, will do anything and turns on a six pence. Fuel is now silly, hence the Combo van with the Isuzu diesel engine. Good work horse, payload, steel and mpg.
Finally the David Brown. Lives outside, reliable, red diesel in tank, allowed 6 miles from farm/ land ? on Red.
Tractors need implements, trailer, transport box, etc etc.
It all takes time to acquire and all needs servicing.
Keep your Vauxhall 1.7. and build from that.
