I'd have to try it out myself, I'm thinking that it should fit. Btw your are giving your W124 E320 battle tank to your son? That's a great car! You'll love the TDI too!
My son is getting my old car, at least for now. I may gradually work to fix some things and may even take the car back someday. My commute just went from 3 miles to 40 miles each way and my car clearly had too many issues to think it could be dependable enough for commuting. My car is perfect for my son's local trips to school, soccer practice, and his girlfriend's house. I know he may destroy the car, but the reality is the car really isn't worth much of anything except to me. I think it is safe vehicle, so that is another good thing for a new driver like my son. My son also thinks it is pretty cool driving around in his father's old Benz that he cared so much about for so many years.
I think I will love my new Golf TDI. I had an old Golf years ago and drove it from coast-to-coast camping in 11 National Parks. I had a lot of fun in the old Golf and this one is going to be a huge step forward compared to that car. I will miss driving my E320, but at least it will still be in my driveway and under my care.
Actually, the new Golf will even be nicer than my old Benz in some ways. I have to admit I still lament the lack of a leather seating option in the TDI, but maybe that will be available in the future. I can imagine someday giving the 2010 Gold TDI to my son and getting a newer version with leather, maybe even a GTD. We will have to wait and see.
Bye the way, I have 5 wheels for my Benz. In fact I have two different sets of 5 wheels for the benz. One set for winter and one set for the rest of the year. I hope to be able to fit a full-size matching Porto in the spare storage area.
