I moved from a V6 Freelander to a 2005 Discovery 3 18 months ago. I have to confess that while it's a truly awesome vehicle. Compared to V6 Freelander, it's an absolute money pit. It's far to fragile for my liking and I'm now seriously thinking of letting it go and returning to a Freelander. It's costs are kept high by what appears to be a deliberate tactic of LR to hike parts prices 3 fold in the last few years on there later vehicles.
As the L322 is similar in design to the D3, it suffers from the same fragility in key areas. These are suspension bushes, compressor, hight sensors and valve blocks. The electronic handbrake (EPB) is a constant head ache, requiring constant maintenance to avoid it jamming on. The drive train is less durable than the Freelander's with an appetite for differentials and gearboxes are common.
Electrical systems are iffy with constant bongs from the on board computer, showing this fault or that.
Don't get me wrong, I love these very advanced LR models. What I don't like is the almost constant need for something to be fixed. I'm in the situation where I can do everything myself, saving on labour costs. If I was paying labour on everything I've done in the last 18 months, the bill would exceed £3K and I've still got a few jobs outstanding.
Just be cautious when moving to these much more expensive LRs as the older they get, more expensive they become. Far more so than the humble Freelander 1.
