Towed for the last 6 years with a VW Jetta Sportwagon TDI. LS8/18 in an Anschau trailer then ASG-29 in a Cobra. Great tow vehicle. I did put spring helpers (coil inserts) in the rear end which helped keep the sag to a minimum. Over the years I've towed with a bunch of VWs starting with a Rabbit Diesel (no good) up through Jetta sedans (fair) Passat V6 wagon with 4 motion (great) and the Sportwagon TDI (great). Pay a lot of attention to the hitch height and tongue weight as well as all the other good advice about tire pressures etc.
