general problems of the 2005 Volkswagen Beetle

My VIN number on car is different from the VIN number on motor. I just found this out about one month ago. I wasn't told this when I bought the vehicle. . So, I don't know if this is a big problem or not. Its a 2005 vw, with a 2004 engine from a slavage yard, bandb, or b and r?? this caused me great alarm. The wiring since had to be done about 2 weeks ago. Also, the belly pan had been missing. I had it fixed. And the headlights had to be repaired too. This car has cost me thousands in repairs since purchase. And I don't have more thousands to put in it. Please help I hope the car in excellent shape now. Also, I noticed the dip stick broke to oil check and hadn't been prior to my acknowledgement. Also, the car has a soft top and I was told was newly replaced in 5/2018. But it seems to have a different look inside then a tight shape regarding top, and I don't know if this should be or not.

When gearing down or starting up at redlight, car downshifts and gears-up with a jerk; took to vw dealer; says it is valve body defect which could utimately cause transmission to go bad; was told at dealership vw knows about the problem and extended a warranty on valve cover only which went out last yr on my vehicle. I never got a notice. Vw admits the problem was there when manufactured in mexico. I believe that this could be a safety issue for many vw owners. Also have had numerous problems with window regulators malfuctioning - affecting locking of doors and window closings- even when these costly regulators are replaced, the problems return. . . My car value is now -0- thanks to vw manufacturing issues.

The first time I drove my used over 50 mph along coastal road (within 24 hours of purchase from a Toyota dealer), the engine cut power and rolled to a stop. From first gear, it began to drive again. I took the car to the dealer and they determined that the valve body was defective. I am scared to drive the car over 55 on the freeway for fear of cutting power. In August 2011, the same cut of power occurred after driving 4 miles in the far right lane on the 405 freeway. I rolled off the freeway offramp and came to a stop. The transmission reset itself and drove up to 40 mph to my destination on side streets. Again the dealer accused the valve body. In July 2012, I decided to let the dealer check the car out again because I had a strange cut in power upon acceleration from a left turn traffic light the previous day. The dealer determined that my fuel pump was defective. After these three fixes, I trust the car to drive around town. But I suffer extreme anxiety about driving the car on a freeway. This week, I need to move the car from California 300 miles to nevada. I am not certain if the transmission can drive that distance without a cut in power. Not dependable, not worth $15,000 price tag. Embarrassment!.
