There are "teething" issues when you buy one of these cars new for a few reasons
1) they are hand-built using a new fiberglass body and a modified beetle pan at least 37 years old. Each car has different fitment issues. Each car has usually a couple or three different assemblers and sometimes things are missed.
2) There aren't any new original VW parts available so the builders have to rely on aftermarket parts that are usually made abroad and are very poorly produced. As hard as they try to use the best available it's still a crap shoot regarding the quality. There are some quality parts still made but they're quite expensive and are usually optioned by the buyer during the build.
3) Most new owners put very few miles on their cars so it takes a while for the bugs to get worked out. I put 5-6,000 miles a year on my car and it still took A while to work all the initial bugs out. But I'm somewhat of an exception as I drive my car pretty hard.
Sometimes the new owner loses interest in his/her new toy because of the initial problems so they dump the car with low miles on them. The next owner picks up the car at a significant savings and usually has very few problems as most of them have been resolved.
My advice? Drive the piss out of it to shake out the gremlins. Better yet, have your boyfriend drive the piss out of it for a couple thousand miles to get the bugs worked out.
Then you'll have your baby all sorted out.
