Volkswagen offers two generations of the Jetta for sale in 1999. The third-generation Jetta has been around since 1993, and it is a carryover for 1999. VW deletes the GT, K2 and GLS models from the lineup, leaving only the GL, GLX, TDI and Wolfsburg models. Later in the model year, the company introduces a completely redesigned Jetta with a smooth new European body, improved versions of the base inline four and the VR6 and a simplified lineup of GL, GLS and GLX models. If you can hold out for a 2000 model, VW will offer a 150-hp 1.8-liter turbo for the GLS.
