I did the exact same thing and....
I am very pleased. I bought a 09 Jetta Sportwagen TDI with 224000 miles. I am the third owner. I had the maintenance records as well... I drove it twice round trip from VA to North Dakota. I got 42 mpg going 75 mph+.
With this high of miles it's all highway.
I believe the most important thing is the proper oil and all the proper interval maintenance being done.
Another thing is I am mechanically inclined and have worked on cars my whole life. If you have to pay to have everything done I believe this car could get expensive and is not for you.
It is all a matter of opinion as you will find . I'm waiting on my vw gift card now...
Oh yes I bought mine in June and it was valued at $10,300- it has gone down in value. I love this car because my other toy is a 2005 Duramax and this Jetta is a sports car compared to that. It is very fun to drive.
Hope this helps.My 2 cents...
