Buy Volksawgen TDIs Before Tax Credit Expires

That is, if you want to cash in on tax credits on Volkswagen's 2010 TDI vehicles before they run out.

Tax credits on these diesel models, ranging from $1,150 for the Touareg 3.0L TDI to $1,700 on the Golf 2.0L TDI automatic, drop by 50 percent come July 1, and disappear altogether after December 31.

The credits are being offered by Uncle Sam to encourage buying fuel-efficient and alternative fuel cars. Typically, these cars are more expensive and the hybrid tax credit is designed to offset that extra cost.

The eligible models and their credits:

2010 Jetta Sedan 2.0L TDI (manual and automatic): Until June 30: $1,300. July 1-Dec. 31: $650.

2010 SportWagen 2.0L TDI (manual and automatic: Until June 30: 1,300. July 1-Dec. 31: $650.
