A salvage title is not a tough deal to pass up,,, personally you may be asking the wrong person,,, I would not consider buying any salvage.
As for a good deal, how good is it really if you will be trying to re-sell down the road with a salvage title ?, 30G is a lot of coin,,, but if you can drive vehicle for 7 - 8 years with no problems your investment will have been valid.
Yes you will be able to insure, but as for a valid warranty,,, NO
If you're still hot to trot - make deal subject to an independent inspection.
