It is always a good idea to avoid vehicles with rebuilt titles:

You get no warranty. Mfg warranty is done. Also the mileage may not reflect what's actually on the engine and transmission. Those could have been damaged and replaced with higher mileage junkyard ones. Could have been a flood car.  Unless it was an older classic car your looking to restore, or something like my wife's Honda Accord (Paid 1000 bucks) I wouldn't consider buying one. You can end up with alignment issues, eat tires, have funky weird electrical issues later from some damaged wiring harness. Just generally not a good idea unless you can get one dirt cheap and are mechanically inclined. Cause you will be turning a wrench on it. 

Even though it looks good who knows the quality of the work and if more problems will arise in the future.  I would walk from both.of them.

I never recommend buying a rebuilt title car.

I wouldn't even recommend buying a clean title Audi. They fall apart without any help. Who knows what Pandora's Box you would open on a rebuilt one. {black}:amazed: {black}:scared:  

I have bought cars with rebuilt titles and you can save a lot of money that way. At the same time I also wouldn't recommend either of those cars regardless of the title. If I had to buy one of those two I would take the Volvo over the Audi.

Out of those 2 I'd go with the Volvo but get a mechanic to look at it if you really want it. I wouldn't recommend it, but if you haven't seen pics of damages at least do a vin lookup maybe you'll see before it was fixed and you'll change your mind. I bought a rebuilt title VW R32 2 years ago and had just 2 suspension problems ($1000 total). A month after I bought, it was in a garage fire and totalled with zero damage so free car. I bought it to replace my totalled Prius. It's been reliable but I still don't recommend buying rebuilt/salvage.

I would never buy rebuild title car,because you never know how big damage was ,and what parts did they use to fix it ,however I bought 2 almost new salvage cars in past with small damage fixed them  and have them for years never had any single problem ,still have them today ,I bought them damaged so i could see what was damaged,i bought all parts myself and it was fixed at my trusted shop,i supervised every step ,now cars are great,I think this is the only way you buy salvage cars,
