I have owned a great running 300D. Very fast for a non-turbo. Then I got the 300TD wagon...which is like a Ferrari by comparison. It is ALOT faster from a dead stop, to about 50 mph or so....nice for freeway onramps and such. Not to mention just better acceleration in any gear, any situation. I strongly recommend the turbo car. If you could not tell the difference between the two, the turbo was not working!<br> Good luck<br> <br> GJ
