Mid to early 90's Vampire movie

[Spenser]

I am trying to remember a movie I saw when I was a kid. I believe it had vampires in it but they were grotesque and monster like. I remember this one family kept their mom up in the attic and fed her from under the door. Later on in the movie the husband of that woman heard her calling to him and he gave in and unlocked the door. To him his wife was beautiful but a quick behind the shot of the wife showed that she was still disgusting looking. Anyway they end up making love and he becomes one too. I also remember that towards the end of the movie the main characters drove this car with a large cross attached to it (I think like a battering ram) straight into a church were the head "vampire" was in.

That's all I remember.

The first part sounds like something like the HP Lovecraft movie the Shuttered Room....Im pretty sure I recall seeing the big cross on the car part....dang!

Ok-wild guess-CHILDREN of the NIGHT (1991)?

CHILDREN OF THE NIGHT did have a car with a cross attached to it like a battering ram.  That's the only thing I remember about the movie.
