HELP! potential first car
 

Hi! I'm new here, and I have to decide if I want this car within the next 2 hours because I have work.

It's a 2003 VW Passat GLX wagon 4motion
just had timing belt replaced
new tires
couple dents can be taken out for this price, but if not it's ~$300 off
141k miles
serviced at a VW dealer

price is $5600, maybe a bit less.

I've read some stuff about oil sludge and things like that. Also, that you need to use premium and a particular type of oil.

Should I jump on it, and if so, what else do I need to know?
I don't speak car.
