S.C,They use nuts and bolts.
Zen, It is the same engine as the Rabbit with a different oil pan and oil pump.
Joe, Just think, If he had the top tied down ,he could have gotten up to maybe 52 mph.
Russ, Your diesel Jetta would feel like a Hemi-'Cuda .
As far as M.P.G. My customer never got over about 20-22 under the best conditions due to having to drive in 2nd and 3rd all the time to get up the hills around here. Sometimes it got less when it got windy or she had more than one person on board. She made pottery and you can just imagine slow the Van got when she loaded it down with that stuff and try to drive to a show. It finally "blew up" after 28,000 miles . She offered to me cheap but I didn't want to ruin my reputation :lol: :lol:
