106 1.5d tud5 will do airship miles normally and spaceship miles if taken care of.
They are slow but I made a cheap induction kit off ebay and it knocked 2 seconds off the 0-60 time.
Also with no turbo you dont need to worry about an expensive bill.
they liked to be revved hard unlike normal diesels so they are quite fun to drive.
Handling is awesome and I got through winter easily with some rainsport 2's on(summer tyres) light car heavy engine on front.
rear seat space is big as it the boot because of no suspension turrets, its got the torsion bar.
Simple to work on, 1 of my injectors was leaking and it still ran fine.
If you have a bosch pump you can run 100% veggie oil perfectly fine, as it loves the veg oil and it has a heated fuel filter.
Gets 60mpg even when ripping it and 70mpg at 40mph on the dual carrige way. 600-800miles on a £40 tank is normal.
Can be tuned it you wanted, NOS is easy and turning up the fuel on the pump.
