You have four car now that that need work or aren't road worthy or have poor gas milage and you want to add a fifth? What are you doing...starting your own bone yard?
Take the $2350 and use it as a down payment. It's not going to get that good a gas milage and you could end up with a money pit even if a tech looks at it.
As stated earlier buy yourself some peace of mind get the new car and pass on this. It's not a good car if a stealership only wants $2350 for it.
