I say go for it... Audi's when in good condition are:
1: Fun as hell to drive
2: SUPER reliable
3: Easy to sell
I'd say it's the better option between the two... it's a great car, as long as all maintenance records are there, and the car is running/driving well.
Best of luck!
I wouldn't say "SUPER" reliable by any means. They are good cars, but let's face it, the car has been modded, and has been beat on. Example: ~I'm selling a Mustang with a blower and slicks, never been tracked~. If it's been modded it's been pushed. My advice is simple just take a good look at the car, and if you are unsure, pay a mechanic 60 bucks to do an inspection on the car. The 60 bucks is well worth knowing if the car is a turd or not.
