well, I just replaced the heater core, it took two days. I'll tell you this much, if this one springs a leak I'm selling it. I had to remove the ENTIRE dashboard, steering wheel and all. TWO DAYS wires, wires, wires. Good god, I've never seen so many wires. My wife came out to check on me and started freaking out when she saw all the wires, and my dash in the back seat. HAHAHAHA. But with the aid of my tattered Bentley manual and that good ole DIY mentality I nailed it. And I saved 1500$ in labor by doing it myself (yeah $1,500, ridiculous huh), those damn vw techs at the dealerships will drain you and most other shops won't touch vw's.
It's crazy, I payed $3,000 for the car 3 years ago and since I've probably spent $6,000 on parts and labor for every thing from a transmission to tires to repairing the wreck damage. If I didn't love this car, I swear......
I had an old 68' bug back in the 90's and parts were more plentiful and cheaper then and still are today, CRAZINESS.
