Volvo C70 (Gen 2)

Owners' Club threads on the 2006-13 C70 describe the full pattern: a mouldy jacket in a boot that looks dry, water dripping from the window-seal join when the car moves, and the car reporting a phantom roof-in-motion warning because moisture has reached the switches. Auto Express’s road test lists wind noise from the A-pillars among the cons. The club’s fix advice is unglamorous - clean and lubricate the seals every year with a proper dressing and keep the drain holes clear with an airline or long cable tie - and it is the difference between a dry car and a corroded electrics bill.

The three-piece metal top takes around 30 seconds and a button sequence to stow, raising the folded stack on a platform to preserve boot space - Parkers notes boot access becomes tricky with the roof down while also praising the mechanism’s weatherproofing versus fabric rivals. Owners' Club threads show the darker side: the car screaming that the roof is mid-opening when it is not, which is the switch cluster or a misread seal, and the diagnosis is fiddly. Buy a car whose roof has cycled cleanly many times in your presence, and confirm the boot tub and platform are undamaged.

Auto Express's review of the 2006-2013 C70 lists wind noise from the A-pillars among the cons, and Volvo Owners Club threads describe door and window seals that harden and leak, letting wind whistle into the cabin at motorway speeds and, in worse cases, water track past the seals. The folding hardtop's seals need annual cleaning and lubrication, and neglected seals can also cause phantom roof-in-motion warning messages. Seal dressing and keeping the drain holes clear with an airline or cable tie is the durable fix.
