Between myself, the wife, and 3 boys, we've had all types of foreign and domestic cars over the years with the exception of GM.
The bottom line is, all dashes deteriorate over the years with temps, sun, an especially if not cared for/cleaned.
**My personal opinion is (formed years ago), if you want your dask to stay nice, and if you want to reduce heat and glare at the front seats in the summer, you should invest in a dash cover of some type.
Since then, I have always sold the vehicles, one at 17 years, with the dash always in "mint" condition.
