I was about to say the same thing! If I wanted a vehicle that was capable around fields, but could thrash along motorways for long distances, I'd go for the Freebie. If I wanted something for more aggresive off road use, I'd look elsewhere.
Always advisable to go for a TD4 if the money stretches that far. On the earlier TD4, lift the fuse box lid on the passenger side of the engine bay and see if it has a white paint dot insode the lid. There was a wiring issue under the box and this shows it has been recalled and corrected.
On 3 door models, check for water ingress in the boot floor cubby box. Also, check the rear screen heater works properly. The wind down rear window rubs it off eventually.
