The 1 ton bag (plus activating all the air bags for a laugh!)should lift a 3 series,maybe even a 5.Just use some 5 gallon drums and lots of ponies!
On a more serious note,once they've lifted em',give it a couple of months then watch out for "special offers" at your dealers...and cheap luxury cars(imported from Atlantis...tax free)probably with intermittent electrical faults and a radio active Cod in the boot!Don't think I'd lke to try and "dry out"a fully loaded new car.
The cars will all be lying on top of each other. The supports are only meant to stop them sliding to and fro, not a full 90 degree list. I reckon the salvys will remove the buggies, shove them to one side, and try and lift the vessell. This would make it easier for you to recover a knackered car, but it would still be a fun dive.
How about a set of four alloy wheels? You don't even need a lifting bag - I reckon they will still be in good enough nick to get a couple of hundred quid per set - that would pay for a nice diving trip somewhere! Not sure what the receiver of wreck would say...
A deal has been struck with a consortium of salvage firms to raise the wreck of the Tricolor, a car-carrier which sank in the Channel 30 miles east of the Kent coast, said Wilhelmsen, the Norwegian owners."
It was agreed a while ago Bren. AFAIK they are going to cut her into 3 parts. It's not so much a salvage operation, more to move her out of the shipping lane. If memory serves correct it's a big U-shaped cable-saw thingy that they pull back and forward beneath her to cut her apart and then lift the easier to manage lumps. It will leave a lot of interesting debris though.
