this means "great sentimental value" ;-)

Hi! This ad says :

For sale
Peugeot 403. 406250 miles.
Grand sentimental value
Tribute to the unforgettable interpreter of Columbo

Thanks! So I got the gist of it. Great sentimental value, indeed.

Also, I love that car. *wipes sentimental tear*

Cool car. I liked Peter Falk. Columbo was good but I liked some of the wacky characters he played, i.e., Cab Driver in It's a Mad Mad Mad Mad World (1963) and others that my too caffeinated tired brain can't recall.

What kind of over formal dictionary does google use? I got the same result, "sentimental" by not taking it's advice of passing thru "sentim" untranslated and I already knew "Gde" is abbreviation for "Grande" even it google did not.
