Extended temperature SBC - at least -20c to 75c

I have used an Intel NUC mini PC to develop my dash but can not use it in the car because it is certified for use only between 0c and 35c and in my location the car interior can be well outside those limits. Does anyone know of an extended temperature (at least -20c to 70c) Linux-supported SBC or mini-PC at reasonable cost?

Thanks.
