For the Getz, the chassis doesn't quite have the bones to utilize the CRDi's power. The shocks are just too limp. I'd actually go for the Getz 1.1. I like the interior better, and the only item it doesn't have is power mirrors (and honestly, if you're the only driver... how often do you adjust your mirrors?). And the 1.1 has a tasty all black interior, while the 1.5 CRDi has cheapo chrome door handles and silver trim. Yes, cheapo chrome. I hate chrome interior handles because the chrome just doesn't stick. One or two years of use and it'll start flaking, and you can cut yourself on the edges. Ask anyone who's had a car with plastic chrome-plated handles.

The Getz 1.1 has less power than the CRDi, but better throttle response. Fuel economy is also pretty good (roughly the same as the Jazz... as long as you don't drive it hard). It's also a lot cheaper than either the Jazz or the CRDi.

If you're choosing the CRDi for driving excitement, I'd rather get an MT Jazz 1.5. Not as torquey but much better handling and great top end zing.
