Had ours 2 years now, no water ingress here, in the interior or the boot. Occasional rattles from the roof when it's up, yes lol. As has been mentioned the suspension takes a pounding as it's quarter of a ton heavier than the car it's based on, the S40, we've had to replace the coil springs all round as they've all broken at some point. Also the aircon condenser is a weak point (so check that the A/C blows cold) & the rechargeable battery in the alarm siren module (alarm will sound for no reason when car is locked). Other than that it's been the usual consumables, front brake discs, pads & tyres. They're not really a driver's car, more of a top-down cruiser, although with the T5 obviously you've got the oomph
