2009 Cadillac CTS 4dr Sedan w/Direct Injection (3.6L 6cyl 6A)
Straight through the gas spike crisis, this car managed approx 21MPG pretty hard driving. The vehicle tracks incredibly on the highway and might have the best overall feel of any car we purchased including nearly every foreign brand.
Standard V-6 is outstanding. No need for the DI, save the money because the speed and power of standard is plenty offering solid MPG. Seat comfort and night interior lighting are excellent.
For safety, mandatory missing backup sensors. Come on GM that has to be standard on Cadillac. We absolutely love this car and shockingly can't come up with any complaints!
