I bought a 3 door fl1 but now wish I'd bought a 5 door. Accessing the back seats is a pain and you need to practically dislocate your shoulder to get at the seat belt.
When they are working correctly, the V6 is by far the nicest Freelander to drive. My V6 did 19.9 Mpg on my 10 mile Cornish B road commute. I still love driving the V6 (now the mother in law's) whenever I need to work on it.
I now have an 05 TD4 SE auto with the winter pack fitted. It does 29 Mpg, so 10 Mpg better than the V6. However the V6 is a nicer drive and is much more refined and a lot less noisy.
I'd buy another 1.8 in a heartbeat but SWMBO didn't like it. Don't rush into a purchase though as there are loads out there and a rough one could end up costing a lot more than you bargain for.
Be aware a head gasket change will cost you around £150 by the time you account for everything. Then there is the timing belt and water pump plus oil for engine, gearbox, IRD and diff if you want to go that far.
