<human>: Can you condense the text into a few key points?

I have the option right now to go after a 2006 grand prix with 127k miles that's 4500, or go after 2013 Dodge dart with 27k miles and is still under the 100k warranty and has a brand new stock turbo and a piece that was fixed in the transmission that was giving it issues. The car was taken in under lemon law for a defective turbo. They replaced it with a brand new one and did something to the transmission and put a brand new battery in it. It's listed for 11,500 which is 4000 under nada or kbb. With grand prix's on the other hand, they need their transmissions flushed every 100k or 5years, whichever is first. It hasn't been done to it to their knowledge in 4 years and 40k of miles. Also, the transmissions and water pumps usually go out at around 150,000 but if taken care of and properly maintained, can make it to 250,000. But really, what are the chances they drove it nice? Especially since it's a college guy who's single.
<bot>: grand prix that could be a money pit for 4500 or possibly reliable for up to 200k, or a dodge dart that's 4k below nada and closely looked at and inspected by Chrysler.
